The Analysis of Repeated Categorical Measurements Subject to Nonignorable Nonresponse
本文扩展了条件似然方法，使其能处理部分分类的重复测量数据，并允许无应答机制可忽略或不可忽略，用标准统计软件即可计算。
Abstract Conditional likelihood methods have been proposed for analyzing the repeated measurement of categorical responses. This article extends the methods to include partially classified subjects. The extension allows for an ignorable or nonignorable nonresponse mechanism and uses standard statistical software for the computations. Two examples of incomplete longitudinal categorical data illustrate the method.
