This is a nonignorable missingness mechanism, in that nonresponse for any item can depend on values of other items that are themselves missing. We show that, under this itemwise conditionally independent nonresponse assumption, one can define and identify nonparametric saturated classes of joint multivariate models for the study variables and their missingness indicators. We also show how to perform sensitivity analysis to violations of the conditional independence assumptions encoded by this missingness mechanism. Throughout, we illustrate the use of this modeling approach with data analyses.}, keywords = {Loglinear model, Missing not at random, Missingness mechanism, Nonignorable, Nonparametric saturated, Sensitivity analysis}, doi = {10.1093/biomet/asw063}, url = {https://doi.org/10.1093/biomet/asw063}, author = {M.

The basic idea is (i) to create completed samples by imputing nonrespondents{\textquoteright} data under various assumptions about the nonresponse mechanisms, (ii) take hypothetical samples of varying sizes from the completed samples, and (iii) compute and compare measures of accuracy and cost for different proposed sample sizes. As part of the methodology, we present a new approach for generating imputations for multivariate continuous data with nonignorable unit nonresponse. We fit mixtures of multivariate normal distributions to the respondents{\textquoteright} data, and adjust the probabilities of the mixture components to generate nonrespondents{\textquoteright} distributions with desired features. We illustrate the approaches using data from the 2007 U. S. Census of Manufactures. }, keywords = {Methodology}, url = {http://arxiv.org/abs/1511.02189}, author = {T. Paiva and J.P.
