f_test

F-test for equal variances (two-tailed p-value).

Syntax

v = f_test(array1, array2)

Description

Returns the two-tailed probability that the variances of the two samples are equal. Smaller values indicate stronger evidence that variances differ.

Example

f_test([1 2 3 4 5], [10 20 30 40 50])
