LSD test in Proc Mixed

macambareri — Sun, 15 Jul 2018 14:00:21 GMT

It is possible making LSD Fisher comparision in Proc mixed, printing letters of the results? Can anyone help me?

I´m analizing a split plot design.

Thanks!

If your experiment fits the assumptions of PROC GLM, you could do it there. If your data is not normally distributed, or you need PROC MIXED because you have correlation in your data or non-constant variability, I don't think the LSD test exists.

Many Thanks! Thankfully data is normally distributed. And how the sentence should be for do the LSD test adding letters to the comparisons?
Thanks

Yes you can do this in PROC GLM if it meets the requirements of the analysis. If it does not meet the requirements, then I believe you are stuck with PROC MIXED and no LSD test or letters.
