Hai jay,
 
Thanks for the reply.The problem with GEE is that it cannot handle
missing values. We have to remove all the missing values before the
analysis and this in turn will lead to unequal time points and hence,
 be able to try only identity or an exchangeable covariance matrix for
the repeated observations.
