Does the Fit Model platform with the Mixed Model personality provide letters showing which means are significantly different when you do a multiple comparison test?
The mixed model personality in Fit Model does not produce a connecting letters report for multiple comparison procedures at this time. When I first started using the mixed model personality I also missed the connecting letters report (it really is useful), but have grown quite fond of the Pairwise Comparisons Scatterplot, which gives even more information at a glance.
If you would like, I would be happy to submit a feature request to add an option for the connecting letters report in the mixed model personality.
Thanks so much for your response.
Please do submit a feature request to add the connecting letters report to the mixed model personality. When you are graphing treatment means, it is very convenient to have the connecting letters report so that one can easily add these letters to the graph. It is now quite inconvenient. I am really surprised that SAS didn't include this great feature into JMP12.
I'll do that for you. I also use the connecting letters report for making charts; it's a pretty indispensable tool and I'm sure others will find it useful to be included in the new mixed model personality.
Has there been any progress on adding the connecting letters report to mixed effects model results?
