File Information
Description

This script helps to investigate properties of a paired Wilcoxon signed-rank test on artificial data generated from the continuous uniform distributions with different upper endpoints.

Parameters of the model are defined and described in section "Experiment parameters initialization".

The script generates 3 pseudocolor plots, which are:
* P-values for Wilcoxon signed rank test depending on N and MU2;
* Average P-values for Wilcoxon signed rank test over Number_of_Exprs experiments depending on N and MU2;
* Emperical Power for Wilcoxon signed rank test over Number_of_Exprs experiments depending on N and MU2.
