Proc Mixed for >2 treatments [Software]
Dear matz!
As my subject line already said: 'Proc Miced for >2treatments'
In a 2x2 study there is no information which can be 'recovered' by using Proc MIXED - you simply have no test/reference ratio for drop-outs (incomplete samples). Therefore these subjects are omitted in both methods - giving identical results.
Only for more than 2 treatments. Please reread my previous post and the linked ones as well...

❝ I used both MIXED and GLM procedure to analyse the data of a 2x2 design with missing values. But both procedure gave me the same result (i.e; 90%C.I and ANOVA table).

❝ So what is the advantage of using MIXED procedure for missing data set? ....Is there any particular reason for using MIXED procedure for analysing missing data sets?
