A Semiparametric Approach for Analyzing Nonignorable Missing Data

Xie, Hui; Qian, Yi; Qu, Leming - 2011

In missing data analysis, there is often a need to assess the sensitivity of key inferences to departures from untestable assumptions regarding the missing data process. Such sensitivity analysis often requires specifying a missing data model that commonly assumes parametric functional forms for...
