HI,

I am working with a longitudinal survey data with two time points for now. I am interested in looking at the differences betwen these two time points (Mostly ordinal outcomes). I have two seperate weights for each time point. Can anyone advice me on how I should proceed with this. I have worked with survey data and longitudinal data seperately but never with longitudinal survey data. I use SAS and SAS Callable SUDAAN. I found one article where they used Proc Surveylogistic with ID as a cluster variable.

Any pertinent information would be greatly appreciated.

Thanks so much for your time -Kamala
