Dr. Roderick Little Presents 'Proxy Pattern-Mixture Analysis for Survey Nonresponse'.
On September 12th, 2008, The School of Public Health Dr. Roderick Little Presents 'Proxy Pattern-Mixture Analysis for Survey Nonresponse'. Propose a new method, proxy pattern-mixture analysis, for the assessment of nonresponse bias for the mean of a survey variable Y subject to nonresponse. The method integrates into a single analysis the three key features of the problem, the nonresponse rate, differences of the distribution of covariates between respondents and nonrespondents, and the extent to which these covariates predict survey outcomes.
