SEMIPARAMETRIC ANALYSIS
OF MULTIVARIATE PANEL COUNT DATA
WITH APPLICATION TO A PSORIATIC ARTHRITIS STUDY

by

Jianguo Sun
University of Missouri


Abstract

This talk discusses regression analysis of multivariate panel count data that occur in, for example, prospective studies involving recurrent events that are only detected and recorded at periodic assessment times. Examples of such data arise in diverse areas such as epidemiological studies, medical follow-up studies, reliability studies, and tumorigenicity experiments. For the analysis, a class of marginal mean models is proposed which leave the dependence structures for related types of recurrent events completely unspecified. Estimating equations are developed for regression parameters and the resulting estimates are shown to be consistent and asymptotically normal. A motivating example, from a study of patients with psoriatic arthritis, is presented and analyzed by using the proposed methodology.
