(R.D. Wolfinger and M. Chang. Comparing the SAS GLM and MIXED procedures
for repeated measures. Technical report, SAS Institute Inc., Cary, NC,
) and saw on expression on page 10th . in 6th row (PROC MIXED) in
table 1 (Can produce sphericity test results either by running both
TYPE=UN and TYPE=HF or by using TYPE=UN on transformed data). I applied
the expression but I got on error message so I couldn’t get any result
please, could you help me how to solve this problem.
What I can add to the under code, that I see the results of the
sphericcity test results.
I have a code block as shown following, what code do I need to solve my
problem thank you.
