Erin:
I found your suggestions for getting the robust std. errors quite helpful;
thanks. A question: while using the glee package. we have to identify this
argument, called "id." I understand it to be the length of the rows;
correct? I am sure that is not the case since that doesn't seem to be
working. Additionally, I am assuming that for the argument "corstr", it is
best to put "independence" if the model assumes independence?
Thank you for your help
Regards
Yousuf
