# scipy.stats.mstats.obrientransform

`scipy.stats.mstats.``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.

  Returns: transformed data for use in an ANOVA
