Dear List I am using the gee package and want to specify my own correlation structure using the corstr(fixed) option.
Can anybody advise me how exactly I need to define the structure I want? Do I create a matrix myself? How can I get the command to realise it needs to use my own matrix? Many thanks Lauar ______________________________________________ [EMAIL PROTECTED] mailing list http://www.stat.math.ethz.ch/mailman/listinfo/r-help
