This group contains a statistics library, which offers several basic methods and is based on an iterator interface:

- \ref jkqtptools_math_statistics_1dhist

.
All statistics functions use an iterator-based interface, comparable to the interface of the <a href="http://www.cplusplus.com/reference/algorithm/">algorithms in the C++ standard template library</a>. To this end, the class `JKQTPDatastore` provides an iterator interface to its columns, using the functions `JKQTPDatastore::begin()` and `JKQTPDatastore::end()`. Both functions simply receive the column ID as parameter and exist in a const and a mutable variant. the latter allows to also edit the data. In addition the function `JKQTPDatastore::backInserter()` returns a back-inserter iterator (like generated for STL containers with `std::back_inserter(container)`) that also allows to append to the column.
Note that the iterator interface allows to use these functions with any container that provides such iterators (e.g. `std::vector<double>`, `std::list<int>`, `std::set<float>`, `QVector<double>`...).
Code using one of these statistics functions therefore may look e.g. like this:
\code
// mean of a column in a JKQTPDatastore:
double mean=jkqtpstatAverage(datastore1->begin(randomdatacol1), datastore1->end(randomdatacol1));
// mean of a std::vector
std::vector<double> data {1,2,4,5,7,8,10,2,1,3,5};
double meanvec=jkqtpstatAverage(data.begin(), data.end());
\endcode
All statistics functions use all values in the given range and convert each value to a `double`, using `jkqtp_todouble()`. The return values is always a dohble. Therefore you can use these functions to calculate statistics of ranges of any type that can be converted to `double`. Values that do not result in a valid `double`are not used in calculating the statistics. Therefore you can exclude values by setting them `JKQTP_DOUBLE_NAN` (i.e. "not a number").

Note that this operation changes the column length (number of rows). If the memory was externally managed before, it will be internally managed afterwards!

Alterantively there is also a `std::back_inserter`-like interface to append to a column:

# Tutorial (JKQTPlotter): Advanced 1-Dimensional Statistics with JKQTPDatastore {#JKQTPlotterBasicJKQTPDatastoreStatistics}
This tutorial project (see `./examples/simpletest_datastore_statistics/`) explains several advanced functions of JKQTPDatastore in combination with the statistics library conatined in JKQTPlotter.
[TOC]
The source code of the main application can be found in [`jkqtplotter_simpletest_datastore_statistics.cpp`](https://github.com/jkriege2/JKQtPlotter/tree/master/examples/simpletest_datastore_statistics/jkqtplotter_simpletest_datastore_statistics.cpp).
This tutorial cites only parts of this code to demonstrate different ways of working with data for the graphs.
## Generating different sets of random numbers
The code segments below will fill four instances of JKQTPlotter with different statistical plots. All these plots are based on three sets of random numbers generated as shown here:
```.cpp
size_t randomdatacol1=datastore1->addColumn("random data 1");
size_t randomdatacol2=datastore1->addColumn("random data 2");
size_t randomdatacol3=datastore1->addColumn("random data 3");
std::random_device rd; // random number generators:
std::mt19937 gen{rd()};
std::uniform_int_distribution<> ddecide(0,1);
std::normal_distribution<> d1{0,1};
std::normal_distribution<> d2{6,1.2};
for (size_t i=0; i<150; i++) {
double v=0;
const int decide=ddecide(gen);
if (decide==0) v=d1(gen);
else v=d2(gen);
datastore1->appendToColumn(randomdatacol1, v);
if (decide==0) datastore1->appendToColumn(randomdatacol2, v);
else datastore1->appendToColumn(randomdatacol3, v);
}
```
The column `randomdatacol1` will contain 150 random numbers. Each one is drawn either from a normal dirstribution N(0,1) (`d1`) or N(6,1.2) (`d2`). the decision, which of the two to use is based on the result of a third random distribution ddecide, which only returns 0 or 1. The two columns `randomdatacol2` and `randomdatacol3` only collect the random numbers drawn from `d1` or `d2` respectively.
The three columns are generated empyt by calling `JKQTPDatastore::addColumn()` with only a name. Then the actual values are added by calling `JKQTPDatastore::appendToColumn()`.
## Basic Statistics
The three sets of random numbers from above can be visualized e.g. by a `JKQTPPeakStreamGraph` graph with code as follows:
```.cpp
JKQTPPeakStreamGraph* gData1;
plot1box->addGraph(gData1=new JKQTPPeakStreamGraph(plot1box));
gData1->setDataColumn(randomdatacol1);
gData1->setBaseline(-0.1);
gData1->setPeakHeight(-0.05);
gData1->setDrawBaseline(false);
```
This (if repeated for all three columns) results in a plot like this:
![jkqtplotter_simpletest_datastore_statistics_dataonly](https://raw.githubusercontent.com/jkriege2/JKQtPlotter/master/screenshots/jkqtplotter_simpletest_datastore_statistics_dataonly.png)
Based on the raw data we can now use JKQTPlotter's statistics library to calculate some basic properties, like the average (`jkqtpstatAverage()`) or the standard deviation (`jkqtpstatStdDev()`):
```.cpp
size_t N=0;
double mean=jkqtpstatAverage(datastore1->begin(randomdatacol1), datastore1->end(randomdatacol1), &N);
double std=jkqtpstatStdDev(datastore1->begin(randomdatacol1), datastore1->end(randomdatacol1));
```
Both statistics functions (the same as all statistics functions in the library) use an iterator-based interface, comparable to the interface of the algorithms in the C++ standard template library. To this end, the class `JKQTPDatastore` provides an iterator interface to its columns, using the functions `JKQTPDatastore::begin()` and `JKQTPDatastore::end()`. Both functions simply receive the column ID as parameter and exist in a const and a mutable variant. the latter allows to also edit the data. In addition the function `JKQTPDatastore::backInserter()` returns a back-inserter iterator (like generated for STL containers with `std::back_inserter(container)`) that also allows to append to the column.
note that the iterator interface allows to use these functions with any container that provides such iterators (e.g. `std::vector<double>`, `std::list<int>`, `std::set<float>`, `QVector<double>`...).
The output of these functions is shown in the image above in the plot legend/key.
Of course, several other functions exist that calculate basic statistics from a column, e.g.:
- average/mean: `jkqtpstatAverage()`, `jkqtpstatWeightedAverage()`
- number of usable values in a range:`jkqtpstatCount()`
- minimum/maximum: `jkqtpstatMinMax()`, `jkqtpstatMin()`, `jkqtpstatMax()`
- sum: `jkqtpstatSum()`
- variance: `jkqtpstatVariance()`, `jkqtpstatWeightedVariance()`
- standard deviation: `jkqtpstatStdDev()`, `jkqtpstatWeightedStdDev()`
- skewnes`jkqtpstatSkewness()`
- statistical moments: `jkqtpstatCentralMoment()`, `jkqtpstatMoment()`
- correlation coefficients: `jkqtpstatCorrelationCoefficient()`
- median: `jkqtpstatMedian()`
- quantile: `jkqtpstatQuantile()`
- (N)MAD: `jkqtpstatMAD()`, `jkqtpstatNMAD()`
- 5-Number Summary (e.g. for boxplots): `jkqtpstat5NumberStatistics()`, `jkqtpstat5NumberStatisticsAndOutliers()`, `jkqtpstat5NumberStatisticsOfSortedVector()`, `jkqtpstat5NumberStatisticsAndOutliersOfSortedVector()`
All these functions use all values in the given range and convert each value to a `double`, using `jkqtp_todouble()`. The return values is always a dohble. Therefore you can use these functions to calculate statistics of ranges of any type that can be converted to `double`. Values that do not result in a valid `double`are not used in calculating the statistics. Therefore you can exclude values by setting them `JKQTP_DOUBLE_NAN` (i.e. "not a number").

As mentioned above and shown in several other examples, JKQTPlotter supports [Boxplots](https://en.wikipedia.org/wiki/Box_plot) with the classes `JKQTPBoxplotHorizontalElement`, `JKQTPBoxplotVerticalElement`, as well as `JKQTPBoxplotHorizontal` and `JKQTPBoxplotVertical`. You can then use the 5-Number Summray functions from the statistics library to calculate the data for such a boxplot (e.g. `jkqtpstat5NumberStatistics()`) and set it up by hand. Code would look roughly like this:
```.cpp
JKQTPStat5NumberStatistics stat=jkqtpstat5NumberStatistics(data.begin(), data.end(), 0.25, .5);
JKQTPBoxplotVerticalElement* res=new JKQTPBoxplotVerticalElement(plotter);
res->setMin(stat.minimum);
res->setMax(stat.maximum);
res->setMedian(stat.median);
res->setMean(jkqtpstatAverage(first, last));
res->setPercentile25(stat.quantile1);
res->setPercentile75(stat.quantile2);
res->setMedianConfidenceIntervalWidth(stat.IQRSignificanceEstimate());
res->setDrawMean(true);
res->setDrawNotch(true);
res->setDrawMedian(true);
res->setDrawMinMax(true);
res->setDrawBox(true);
res->setPos(boxposX);
plotter->addGraph(res);
```
In order to save you the work of writing out this code, the statistics library provides "adaptors", such as `jkqtpstatAddVBoxplot()`, which basically implements the code above. Then drawing a boxplot is reduced to:
```.cpp
JKQTPBoxplotHorizontalElement* gBox2=jkqtpstatAddHBoxplot(plot1box->getPlotter(), datastore1->begin(randomdatacol2), datastore1->end(randomdatacol2), -0.25);
gBox2->setColor(gData2->getKeyLabelColor());
gBox2->setBoxWidthAbsolute(16);
```
Here `-0.25`indicates the location (on the y-axis) of the boxplot. and the plot is calculated for the data in the `JKQTPDatastore` column `randomdatacol2`.

### Boxplots with Outliers
Usually the boxplot draws its whiskers at the minimum and maximum value of the dataset. But if your data contains a lot of outliers, it may make sense to draw them e.g. at the 3% and 97% quantiles and the draw the outliers as additional data points. This can also be done with `jkqtpstat5NumberStatistics()`, as you can specify the minimum and maximum quantile (default is 0 and 1, i.e. the true minimum and maximum) and the resulting object contains a vector with the outlier values. Then you could add them to the JKQTPDatastore and add a scatter plot that displays them. Also this task is sped up by an "adaptor". Simply call
```.cpp
std::pair<JKQTPBoxplotHorizontalElement*,JKQTPSingleColumnSymbolsGraph*> gBox1;
gBox1=jkqtpstatAddHBoxplotAndOutliers(plot1box->getPlotter(), datastore1->begin(randomdatacol1), datastore1->end(randomdatacol1), -0.3,
0.25, 0.75, // 1. and 3. Quartile for the boxplot box
0.03, 0.97 // Quantiles for the boxplot box whiskers' ends
);
```
As you can see this restuns the `JKQTPBoxplotHorizontalElement` and in addition a `JKQTPSingleColumnSymbolsGraph` for the display of the outliers. The result looks like this:
![jkqtplotter_simpletest_datastore_statistics_boxplots_outliers](https://raw.githubusercontent.com/jkriege2/JKQtPlotter/master/screenshots/jkqtplotter_simpletest_datastore_statistics_boxplots_outliers.png)
## Histograms
Calculating 1D-Histograms is supported by several functions from the statistics library, e.g. `jkqtpstatHistogram1DAutoranged()`. You can use the result to fill new columns in a `JKQTPDatastore`, which can then be used to draw the histogram (here wit 15 bins, spanning the full data range):
```.cpp
size_t histcolX=plotter->getDatastore()->addColumn(histogramcolumnBaseName+", bins");
size_t histcolY=plotter->getDatastore()->addColumn(histogramcolumnBaseName+", values");
jkqtpstatHistogram1DAutoranged(first, last, plotter->getDatastore()->backInserter(histcolX), plotter->getDatastore()->backInserter(histcolY), 15);
JKQTPBarVerticalGraph* resO=new JKQTPBarVerticalGraph(plotter);
resO->setXColumn(histcolX);
resO->setYColumn(histcolY);
resO->setTitle(histogramcolumnBaseName);
plotter->addGraph(resO);
```
Again there are "adaptors" which significanty reduce the amount of coude you have to type:
```.cpp
JKQTPBarVerticalGraph* hist1=jkqtpstatAddHHistogram1DAutoranged(plot1->getPlotter(), datastore1->begin(randomdatacol1), datastore1->end(randomdatacol1), 15);
```
The resulting plot looks like this (the distributions used to generate the random data are also shown as line plots!):
![jkqtplotter_simpletest_datastore_statistics_hist](https://raw.githubusercontent.com/jkriege2/JKQtPlotter/master/screenshots/jkqtplotter_simpletest_datastore_statistics_hist.png)
## Kernel Density Estimates (KDE)
Especially when only few samples from a distribution are available, histograms are not good at representing the underlying data distribution. In such cases, [Kernel Density Estimates (KDE)](https://en.wikipedia.org/wiki/Kernel_density_estimation) can help, which are basically a smoothed variant of a histogram. The statistics library supports calculating them via e.g. `jkqtpstatKDE1D()`:
```.cpp
size_t kdecolX=plotter->getDatastore()->addColumn(KDEcolumnBaseName+", bins");
size_t kdecolY=plotter->getDatastore()->addColumn(KDEcolumnBaseName+", values");
jkqtpstatKDE1D(first, last, -5.0,0.01,10.0, plotter->getDatastore()->backInserter(kdecolX), plotter->getDatastore()->backInserter(kdecolY), kernel, kdeBandwidth);
JKQTPXYLineGraph* resO=new JKQTPXYLineGraph(plotter);
resO->setXColumn(kdecolX);
resO->setYColumn(kdecolY);
resO->setTitle(KDEcolumnBaseName);
resO->setDrawLine(true);
resO->setSymbolType(JKQTPNoSymbol);
plotter->addGraph(resO);
```
The function accepts different kernel functions (any C++ functor `double f(double x)`) and provides a set of default kernels, e.g.
- `jkqtpstatKernel1DEpanechnikov()`
- `jkqtpstatKernel1DGaussian()`
- `jkqtpstatKernel1DUniform()`
- ...
The three parameters `-5.0, 0.01, 10.0` tell the function `jkqtpstatKDE1D()` to evaluate the KDE at positions between -5 and 10, in steps of 0.01.
Finally the bandwidth constrols the smoothing and the statistics library provides a simple function to estimate it automatically from the data:
```.cpp
double kdeBandwidth=jkqtpstatEstimateKDEBandwidth(datastore1->begin(randomdatacol1subset), datastore1->end(randomdatacol1subset));
```
Again a shortcut "adaptor" simplifies this task:
```.cpp
JKQTPXYLineGraph* kde2=jkqtpstatAddHKDE1D(plot1kde->getPlotter(), datastore1->begin(randomdatacol1subset), datastore1->end(randomdatacol1subset),
// evaluate at locations between -5 and 10, in steps of 0.01 (equivalent to the line above, but without pre-calculating a vector)
-5.0,0.01,10.0,
// use a gaussian kernel
&jkqtpstatKernel1DEpanechnikov,
// estimate the bandwidth
kdeBandwidth);
```
Plots that result from such calls look like this:
![jkqtplotter_simpletest_datastore_statistics_kde](https://raw.githubusercontent.com/jkriege2/JKQtPlotter/master/screenshots/jkqtplotter_simpletest_datastore_statistics_kde.png)
## Cummulative Histograms and KDEs
Both histograms and KDEs support a parameter `bool cummulative`, which allows to accumulate the data after calculation and drawing cummulative histograms/KDEs:
```.cpp
JKQTPBarVerticalGraph* histcum2=jkqtpstatAddHHistogram1DAutoranged(plot1cum->getPlotter(), datastore1->begin(randomdatacol2), datastore1->end(randomdatacol2),
// bin width
0.1,
// normalized, cummulative
false, true);
```

@ -10,7 +10,7 @@ Adding an evaluated funtion to a graph is very simple:
parsedFunc->setFunction("sin(x*8)*exp(-x/4)");
parsedFunc->setTitle("user function");
```
As you can see a graph of the type `JKQTPXParsedFunctionLineGraph` is used, which plots a function that depends on the variable `x`. The given function is parsed and evaluated (see [`lib/jkqtplottertools/jkqtpmathparser.h`](https://github.com/jkriege2/JKQTPlotter/blob/master/lib/jkqtplottertools/jkqtpmathparser.h) for details on the features of the math parser). An intelligent drawing algorithm chooses the number of control points for drawing a smooth graph, with sufficient amount of details, by evaluating locally the slope of the function.

- `jkqtplotter.pri` contains all files in this library, including `JKQTFastPlotter` and `JKQTMathText`
- `jkqtfastplotter.pri` contains only those files from this directory which are necessary to build `JKQTFastPlotter`

- `jkqtpcommon.pri` common support library for all libraries above (math tools, basic drawing tools, ...)
### Build static libraries
In the directory [`../staticlib`](../staticlib) you will find several Project files that build a static library of the full JKQTPlotter (including JKQTFastPlotter and JKMathText), or of subsets of this library. You can then link against these libs in your project.
