I am doing the longitudinal model and I have 2 questions:
1) I am using age in my proc mixed model statement but I need it to be weighted by the sample size of each age cohort. How do I specify this in the proc mixed statement?
2) From what I understand, SAS uses log(1)=0 margin for the estimate output for the p-value.How do I change the margin to log(2)?
