ftest - Fischer ratio

Calling Sequence

f=ftest(samples)
[f,p]=ftest(samples)

Parameters

Description

f=ftest(samples) computes the Fischer ratio of the nc samples whose values are in the columns of the matrix samples . Each one of these samples is composed of nr values. (The Fischer ratio is the ratio between nr times the variance of the means of samples and the mean of variances of each sample)

[f,p]=ftest(samples) gives in p the p-value of the computed Fischer ratio f.
