Extended Mallow’s Cp in GEE: An Application to Maternal Morbidity Data

Abstract

Model selection is a vital issue as models are used for purposes of interpretation or prediction. While there are varieties of model selection
criteria, fewer options for the longitudinal data analysis using Generalized Estimating Equations (GEE). Recently, an extended version of
Mallow’s Cp (GCp) is suggested as model selection criterion which can be used for a marginal longitudinal model like GEE. In this study, an
application of GCp is demonstrated to select underlying model with important covariates associated with pregnancy complications for
Bangladeshi women. Further statistical inferences are drawn for selected model by GEE.
