I have an experiment with two groups under different conditions where a single dependent variable is measured repeatedly at multiple times. It seems the right parametric test to use here is two-factor mixed ANOVA:
"A mixed ANOVA compares the mean differences between groups that have been split on two "factors" (also known as independent variables), where one factor is a "within-subjects" factor and the other factor is a "between-subjects" factor."
However, my data is strongly non-normal (and some of the dependent variables are ordinal anyway).
What is a non-parametric equivalent test to two-factor mixed ANOVA?
