' Data FAIL normality test. Try another transformation.
Warning - The first three homogeneity tests are sensitive to non-normal

data and should not be performed.

' Hartley's test for homogeneity of variance

-------------------------------------------------------------------
' These two tests can not be performed because at Least one group has
zero variance.
' Data FAIL to meet homogeneity of variance assumption.
Additional transformations are useless.
