Generalised quasi-Iikelihood inference in a semi-parametric binary dynamic mixed logit model

摘要

There exists a recent study where dynamic mixed-effects regression models for count data have been extended to a semi-parametric context. However, when one deals with other discrete data such as binary responses, the results based on count data models are not directly applicable. In this paper, we therefore begin with existing binary dynamic mixed models and generalise them to the semi-parametric context. For inference, we use a new semi-parametric conditional quasi-likelihood (SCQL) approach for the estimation of the non-parametric function involved in the semi-parametric model, and a semi-parametric generalised quasi-likelihood (SGQL) approach for the estimation of the main regression, dynamic dependence and random effects variance parameters. A semi-parametric maximum likelihood (SML) approach is also used as a comparison to the SGQL approach. The properties of the estimators are examined both asymptotically and empirically. More specifically, the consistency of the estimators is established and finite sample performances of the estimators are examined through an intensive simulation study.
