Good morning,
I was asked to perform a pre-post analysis with ANOVA in order to see the effect of the treatment on the treated. I thought about running a one way anova with the difference between pre and post values as dependent variable and the treatment dummy as independent but the difference between the means of the two groups are very negligible and i don't obtain any significant results. I saw on youtube that it can be done through ANCOVA but i have only found the procedure to run it on SPSS, and not on Stata.
Thanks in advance for your help!
Tommaso
