Hello community, I am receiving the "stopped because of infinite likelihood" error message and could use your help resolving this issue. I have read other posts on this board and one common suggestion is to check that there are no duplicate entries for a subject. I have ensured that each subject has only one value per time point. I am hoping you all might be able to help me figure out what else could be causing this error. Below is an explanation of my design and some samples of my data and code. Anyone advice you could give would be greatly appreciated. Thank you! To give you some more background on my design and code: I am running a 3-way ANOVA (Age | Diet | Time) with repeated measures on Time using Proc Mixed. Each subject, is assigned to one age (2 levels) and one diet (2 levels) and have one value per time point (223 sampling times for each subject). Therefore, there are 223 values per subject and a total of 33 subjects (=7392 total lines of data). Here is a sampling of how my data is entered: input slice$ age$ diet$ time slope; cards; 1a Young Control 0.0 106.1145644 1a Young Control 0.3 95.66878936 1a Young Control 0.7 96.04325189 1a Young Control 1.0 95.74211497 1a Young Control 1.3 95.23252855 1a Young Control 1.7 89.55785791 1a Young Control 2.0 98.95222987 And the code for my model: proc mixed data= AgedRepopLTP; class slice age diet time; model slope = age|diet|time / residual; repeated time / subject=slice type=ar(1); random slice; run; run;quit;
