Dear Yung-jin,

❝ Are the following Power to know codes feasible (3-group Parallel)?

Yesss Sir. But only if we assume equal variances within the groups.
I do not have the power _{to know} any way to get unequal variance assumption into Proc GLM.

And at least the mighty FDA does not want it this way from us :no:
