Mixed-effect hybrid models for longitudinal data with nonignorable dropout.
SUMMARY Selection models and pattern-mixture models are often used to deal with nonignorable dropout in longitudinal studies. These two classes of models are based on different factorizations of the joint distribution of the outcome process and the dropout process. We consider a new class of models, called mixed-effect hybrid models (MEHMs), where the joint distribution of the outcome process a...
متن کاملA general class of pattern mixture models for nonignorable dropout with many possible dropout times.
In this article we consider the problem of fitting pattern mixture models to longitudinal data when there are many unique dropout times. We propose a marginally specified latent class pattern mixture model. The marginal mean is assumed to follow a generalized linear model, whereas the mean conditional on the latent class and random effects is specified separately. Because the dimension of the p...
متن کاملIgnorable dropout in longitudinal studies BY MARIA
This paper provides a concise de nition for ignorable dropout. This is done primarily from a frequentist perspective. The de nition of ignorable dropout depends on both the population of inference and the type of statistical methodology used for inference. Di erent types of dropouts are described and compared to those found in the literature. Ignorability conditions are then given for the follo...
متن کاملMixtures of varying coefficient models for longitudinal data with discrete or continuous nonignorable dropout.
The analysis of longitudinal repeated measures data is frequently complicated by missing data due to informative dropout. We describe a mixture model for joint distribution for longitudinal repeated measures, where the dropout distribution may be continuous and the dependence between response and dropout is semiparametric. Specifically, we assume that responses follow a varying coefficient rand...
متن کاملSelective dropout in longitudinal studies 07 / 11 / 2008
Background Participant dropout occurs in all longitudinal studies, and if systematic, may lead to selection biases and erroneous conclusions being drawn from a study. Aims We investigated whether dropout in the Avon Longitudinal Study of Parents And Children (ALSPAC) was systematic or random, and if systematic, whether it had an impact on the prediction of disruptive behaviour disorders. Method...
