Hi, I have implemented a therapeutic intervention on two groups (one is a control group) and tested them in two moments using some assessment tools (with normative data). Now I want to compare the experimental group with the control group using clinical equivalence testing. To do this I need to specify a range of closeness (One for each assessment tool according to the specificity of this same tool) and do two one-tailed tests to test if the two groups are considered clinically equivalent in the first moment and on the end I want to compare the experimental group with the normative data (Here I have to add the mean and standard deviation of the normative sample because I don't have the normative sample).
I know that R has a package named equivalence but I don't know how to do this kind of calculations with it. Is it even possible with the actual packages?
