Non Parametric Statistics

This technique simply calculates variation based on a comparison of all abundances in a time series, and is free of assumptions of an underlying 'normal' distribution. It is more robust that the coefficient of variation CV and/or the standard deviation of log transformed abundances SDL, it is not...

I have used sum of three sinusoids as my data and this program plots single sided PSD at the end. This is a very simple code made to illustrate the algorithm invloved.

In the analysis of designed experiments, the Friedman test is the most common non-parametric test for complete block designs. The Durbin test is a nonparametric test for balanced incomplete designs that reduces to the Friedman test in the case of a complete block design.In a randomized block...

Rank function usually used as the first step in non-parametric tests such as The Kruskal-Wallis (KW)test. It simply give a rank to each observation (increasing order) in the vector taking into consideration the average of duplicated ranks.The main objective of the rank is to avoid data outliers

In statistics, the Kruskald-deOCtWallis one-way analysis of variance by ranks (named after William Kruskal and W. Allen Wallis) is a non-parametric method for testing equality of population medians among groups. It is identical to a one-way analysis of variance with the data replaced by their...
