Abstract:
|
We develop a model based approach to estimate small area cancer risk factor prevalence using information from two surveys. We demonstrate the ability to estimate parameters generated from the assumed model using a Monte-Carlo EM algorithm. The method is investigated using simulation of datasets that are similar to those that would be obtained from the National Health Interview Survey (NHIS) and the Behavioral Risk Factor Surveillance System (BRFSS) surveys. For the simulated data, we assess the accuracy of the parameter estimates and also the accuracy of the county, state, and national estimates.
