Hi, as per my protocol I aimed at running ANCOVA analysis but I have since learned that an appropriate method would be linear mixed effects model. The problem is that I had my power analysis and an experiment done with ANCOVA in mind. Now I would like to know what the minimum detectable effect size is for the sample I have. All the options I find are for the trials with two arms but I have four of them as well as three measurement times, and five outcomes. Can anyone recommend a good tool? I think this can be done in R but I don't use it so I would prefer another way.
