چکیده

We describe generalized linear latent and mixed models (GLLAMMs) and illustrate their potential in epidemiology. GLLAMMs include many types of multilevel random effect, factor and structural equation models. A wide range of response types are accommodated including continuous, dichotomous, ordinal and nominal responses as well as counts and survival times. Multivariate responses can furthermore be of mixed types. The utility of GLLAMMs is illustrated in three applications involving repeated measurements, measurement error and multilevel data.

Parameter Estimation in Spatial Generalized Linear Mixed Models with Skew Gaussian Random Effects using Laplace Approximation

 Spatial generalized linear mixed models are used commonly for modelling non-Gaussian discrete spatial responses. We present an algorithm for parameter estimation of the models using Laplace approximation of likelihood function. In these models, the spatial correlation structure of data is carried out by random effects or latent variables. In most spatial analysis, it is assumed that rando...

Examples of mixed-effects modeling 1 Running head: EXAMPLES OF MIXED-EFFECTS MODELING Examples of mixed-effects modeling with crossed random effects and with binomial data

Psycholinguistic data are often analyzed with repeated-measures analyses of variance (ANOVA), but this paper argues that mixed-effects (multilevel) models provide a better alternative method. First, models are discussed in which the two random factors of participants and items are crossed, and not nested. Traditional ANOVAs are compared against these crossed mixed-effects models, for simulated ...

Generalized Multilevel Structural Equation Modeling

A unifying framework for generalized multilevel structural equation modeling is introduced. The models in the framework, called generalized linear latent and mixed models (GLLAMM), combine features of generalized linear mixed models (GLMM) and structural equation models (SEM) and consist of a response model and a structural model for the latent variables. The response model generalizes GLMMs to...

Bayesian 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...
