@SteveDenham    Thank you very much for providing further and valuable advice.   I used the code that you suggested with a the addition of the cal*Block effect in the random statement, to account for the split-plot design. I am going to compare the outputs, but I could immediately see that the means comparisons differ. Apparently, LSDs cannot be estimated with Proc MIXED.     proc mixed data=sp; class cal K Block; model rend = cal K cal*K; random block cal*Block; lsmeans cal K cal*K/diff ; run; ... View more

@PaigeMiller    Thank you for your help. I have made progress, and now I'm missing only the LSD values to compare the means shown in the last table (page 7 of the output), which corresponds to the cal * K interaction effects. Since the data came from a split-plot design, different error terms must be used, depending on the comparisons of interest. I don't know why I am not getting this part of the results. ... View more

@mkeintz    Thank you for your input that helped me obtain the three K means. However, I am missing the following:   the LSD values to compare the three K means the LSD values to compare the means of the interaction effects between the "cal" and "K" factors (Table in page 7).   ... View more

@mkeintz Thank you for your reply and interest to assist. I am not familiar with the site, and I was just following the options provided. Maybe, if downloading is not convenient, it should be removed as an option. ... View more

Thank you Paige, but that example is for a quadratic-plateau response, and I am interested in a linear-plateau one, i.e. two straight lines. Armando ... View more
