My methodologic research is to develop regression analysis for correlated responses. There are two situations of interest: when observations come in clusters, for example in longitudinal research or in sample surveys; and secondly when a single time series is observed. We have extended generalized linear models (logistic, linear, log-linear and survival models) to be applicable in these cases.
