I have a repeated measures experiment design with two independent variables ('condition' with 2 levels and 'repeat' with 10 levels) and one dependent variable ('performance'). I'd like to know whether condition A and condition B result in equivalent performance.
My question is similar to this one: ANOVA for equivalence testing, except that I have a paired design (i.e. 'condition' is also a repeated measure).
I think some sort of TOST procedure would be appropriate, but I am not sure what test I should use within the procedure. Do I need to use a two-way repeated measures ANOVA? If so, is it possible to construct a confidence interval using such an ANOVA test?
