Identification and Empirical Likelihood Inference in Nonlinear Regression Model with Nonignorable Nonresponse

The identification of model parameters is a central challenge in the analysis of nonignorable nonresponse data. In this paper, we propose a novel penalized semiparametric likelihood method to obtain sparse estimators for a parametric nonresponse mechanism model. Based on these sparse estimators, an...
