Can anyone comment further on Stata's shortcomings wrt ANOVA? 2. One of the chief complaints about SPSS is that the output for many procedures is unwieldy. It often contains a lot of stuff that (a lot of people think) ought to be optional rather than automatic (e.g., multivariate results for repeated measures ANOVA). And on the flip side, there are things that perhaps ought to be automatic that are optional (e.g., cell means for ANOVA models obtained via GLM). Can anyone comment on how Stata's output compares to that of SPSS?
