Hi, I'm a PhD student in Ecology. I've got experiments that follow a two-
way ANOVA design. My variances are unequal even after classic
transformation (sqrt, Log). I would like to use ANOVA using the Optimal
Scaling technique available on SPSS. Does ANOVA with optimal scaling
require equal variances?
Thank you.
Sébastien.
