Generalized Score Test of Homogeneity for Mixed Effects Models
Many important problems in psychology and biomedical studies require testing for overdispersion, correlation and heterogeneity in mixed effects and latent variable models, and score tests are particularly useful for this purpose. But the existing testing procedures depend on restrictive assumptions. In this paper we propose a class of test statistics based on a general mixed effects model to te...
متن کاملGeneralized Score Test of Homogeneity for Mixed Effects
In this document, we introduce five additional examples that motivate our research on testing homogeneity. In particular, we show how to check the assumptions for two linear mixed models to validate the asymptotic distributions of the score test statistics. Then, we give the detailed derivation for the score test statistic. We present the result about the local power of the score test statistic...
متن کاملBayesian Inference for Spatial Beta Generalized Linear Mixed Models
In some applications, the response variable assumes values in the unit interval. The standard linear regression model is not appropriate for modelling this type of data because the normality assumption is not met. Alternatively, the beta regression model has been introduced to analyze such observations. A beta distribution represents a flexible density family on (0, 1) interval that covers symm...
متن کاملGeneralized McNemar’s Test for Homogeneity of the Marginal Distributions
In the matched-pairs data, McNemar’s test (McNemar, 1947) can be applied only to the case in which there are two possible categories for the outcome. In practice, however, it is possible that the outcomes are classified into multiple categories. Under this situation, the test statistic proposed by Stuart (1955) and Maxwell (1970) is useful, it is actually the generalization of the McNemar’s tes...
متن کاملRandom Effects in Generalized Linear Mixed Models
In this chapter, we examine the use of special forms of correlated random e ects in the generalized linear mixed model (GLMM) setting. A special feature of our GLMM is the inclusion of random residual e ects to account for lack of t due to extra variation, outliers and other unexplained sources of variation. For random e ects, we consider, in particular, the correlation structure and improper p...
