One of the central components in the domain of risk prediction involves developing rich statistical models to predict the future risk of disease. The objective of this talk is to describe recent methods for inferring parameters associated with such models using disparate risk factor information available from multiple studies. Meta-analysis is a popular approach for synthesizing information on common parameters of interest across multiple studies due to logistical convenience and statistical efficiency. We will describe a generalization of this approach that allows estimation of parameters associated with a multiple regression model through meta-analysis of studies which may individually have information only on partial sets of the regressors. An application of the method will be illustrated through a real data example involving the development of a breast cancer risk prediction model using disparate risk factor information from multiple studies. Further, we will show how the proposed framework can be used for efficient analysis of data from two-phase epidemiologic designs.
