st: Surival Analysis with weights

["Naresh M. Punjabi, MD, PhD" <npunjabi@jhmi.edu>]

I am using the stcox command with the robust cluster option to obtain the
robust variance-covariance matrix.  Each individual in the study had four
observations and each individual has a weight.

Can  I conduct weight stcox with the robust cluster option

Thank you
