Perform Contrasts with PROC GLM

amarikow57 — Tue, 13 Apr 2021 20:33:59 GMT

I am trying to compare the lifespan of mice in different dietary groups:
1. NP: nonpurified, standard diet with no restriction

2. N/N85: normal diet begore and after (85 kcal/wk) --> control group

3. N/R50: normal diet before weaning, reduced calories (50 kcal/wk) after

4. R/R50: reduced calorie (50 kcal/wk) before and after weaning

5. N/R50 lopro: normal diet before weaning, reduced calories (50 kcal/wk) after with decreased protein content

6. N/R40: normal diet before weaning, severely reduced calories (40 kcal/wk) after

Data:

lifetime: numeric (continuous)

diet1: numeric --> use as factor 1 through 6

Log:

I am not sure what these errors are referring to. I appreciate any feedback. Thank you!

Nevermind... It's the commas. Saw the mistake as it was posting.
