# 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.
