In this paper we investigate the properties of the information matrices and asymptotic covariances of the constrained maximum likelihood estimates (MLE) in case-control studies. Since in a case-control study samples are stratified on case-control status, the sampling scheme is different from the...

In this article, we study a partially linear single-index model for longitudinal data under a general framework which includes both the sparse and dense longitudinal data cases. A semiparametric estimation method based on the combination of the local linear smoothing and generalized estimation...
