Maybe this might help:
I would like to run an ordered multinomial logistic regression model using panel (longitudinal) data.
Can you, please, help doing such a regression analysis? Is it possible to do it with Stata (reoprob? How?) or with SAS or R (how?)?
Thank you for your invaluable help.
Thank you for this paper. Actually, I'm a non-programmer SAS graphical interfaces user (known as SAS Enterprise Guide). So I can't make use of that paper.
However, my problem can be solved if someone can help me declare data to be panel within SAS EG. Anyone knows how to do that, please?
I did a quick search and I saw this on the SAS website:
Do a search of "longitudinal" in the PDF viewer and see what you get (they discuss the field you have to look at, and you can investigate from there).
