Oneway Anova test for equivalence of scale, variance or dispersion

This hypothesis test performs a oneway equivalence anova test on transformed data.

Note, the interpretation of the equivalence margin equiv_margin will depend on the transformation of the data. Transformations like absolute deviation are not scaled to correspond to the variance under normal distribution.
