Beta Binomial Model for Victimization

NCJ Number
Date Published
June 1983
Victimization models are proposed to fit data from the National Crime Survey.

The models incorporate two features. First, victimizations for given housing units are dependent over time, while those from housing unit to housing unit can be independent (conditional on the parameters of the model). Second, there is an explicit way of using victimization information on a given housing unit to help impute missing observations for that housing unit. The first of these goals was met by introducing a beta-binomial model for the number of months in which a given housing unit is victimized. The second goal, however, has not yet been successfully met within the framework of the beta-binomial model. Two references are listed.
