Longitudinal studies often feature incomplete response and covariate data. Likelihood based method such as EM algorithm gives consistent estimators when data are missing at random provided that the response model and the missing covariate model are correctly specified. In this talk I introduce a doubly robust estimation method for longitudinal data with missing response and missing covariate when data are missing at random. This method is appealing in that it can provide consistent estimates if either the missing data model or the missing covariate model is correctly specified. Simulation studies demonstrate that this method performs well in a variety of situations. This is a joint work with Baojing Chen at University of Washington.
