stac.nonparametric_tests.quade_test(*args)[source]

Performs a Quade ranking test. Tests the hypothesis that in a set of k dependent samples groups (where k >= 2) at least two of the groups represent populations with different median values. The difference with a friedman test is that it uses the median for each sample to wiehgt the ranking.

Parameters:

sample1, sample2, ... : array_like

The sample measurements for each group.

Returns:

F-value : float

The computed F-value of the test.

p-value : float

The associated p-value from the F-distribution.

rankings : array_like

The ranking for each group.

pivots : array_like

The pivotal quantities for each group.
