Hello,   I need some help obtaining the random slope estimates per individual, so that I can use those parameters per individual as an outcome in another part of the analysis.   Below is the code that I am currently using:   ods output solutionf=slopes; proc mixed data=trial; class idno time; model GLOBALCOG = time WMFA WMH ICV brainvol AGE RACE GENDER/s chisq OUTPM=WORK.PM RESIDUAL; random intercept time; repeated time/type=un subject=idno r rcorr; run;   The part "solutionf=slopes" provide one parameter of the random slope but not per individual.    Thanks!     ...

Hello,  I need to obtain the residuals and then use them as the outcome in a separate model. In the past, I was able to extract the residuals using proc reg, as shown below:  proc reg data=abstract.pedometer_speedquint2; model stepsperday=stepmin_avg_valid ; OUTPUT out=b r=res; run; proc print data=abstract.pedometer_speedquint2; var r; /*residuals per participant*/ run;   However, I have not been able to figure out how to do the same using proc mixed.   This is the code I am using for the analysis from which I want to extract the residuals:    proc mixed data=trial4; class idno time;  model CASI= time WMFA WMH ICV TOTAL_GM_VOL TOTAL_WM_VOL AGE RACE GENDER/s chisq; repeated time/type=un subject=idno r rcorr; run;   Thanks! ...
