scipy.stats.obrientransform

scipy.stats.obrientransform(*args)

Computes a transform on input data (any number of columns).

Used to test for homogeneity of variance prior to running one-way stats. Each array in *args is one level of a factor. If an F_oneway run on the transformed data and found significant, variances are unequal. From Maxwell and Delaney, p.112.

Parameters :

args : ndarray

Any number of arrays.

Returns :

obrientransform : ndarray

Transformed data for use in an ANOVA.
