Bayesian Inference for Spatial Beta Generalized Linear Mixed Models [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2018
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

Generalized linear mixed models can detect unimodal species-environment relationships [PDF]

open access: yesPeerJ, 2013
Niche theory predicts that species occurrence and abundance show non-linear, unimodal relationships with respect to environmental gradients. Unimodal models, such as the Gaussian (logistic) model, are however more difficult to fit to data than linear ...

Sensitivity analysis for causal effects with generalized linear models

open access: yesJournal of Causal Inference, 2022
Residual confounding is a common source of bias in observational studies. In this article, we build upon a series of sensitivity analyses methods for residual confounding developed by Brumback et al. and Chiba whose sensitivity parameters are constructed

Designs for generalized linear models with random block effects via information matrix approximations [PDF]

open access: yes, 2015
The selection of optimal designs for generalized linear mixed models is complicated by the fact that the Fisher information matrix, on which most optimality criteria depend, is computationally expensive to evaluate.

Quasi-Monte Carlo EM algorithm for MLEs in generalized linear mixed models [PDF]

open access: yes, 1998
Inferences for generalized linear mixed models are greatly hampered by the intractable integrated likelihood. In this paper numerical integration based on Quasi-Monte Carlo method is used to approximate the integral of the EM algorithm and then to fit ...

Using R In Generalized Linear Models [PDF]

open access: yesRevista Română de Statistică, 2015
This paper aims to approach the estimation of generalized linear models (GLM) on the basis of the glm routine package in R. Particularly, regression models will be analyzed for those cases in which the explained variable follows a Poisson or a Negative ...

Tariff Analysis in Automobile Insurance: Is It Time to Switch from Generalized Linear Models to Generalized Additive Models?

open access: yesMathematics, 2023
Generalized Linear Models (GLMs) are the standard tool used for pricing in the field of automobile insurance. Generalized Additive Models (GAMs) are more complex and computationally intensive but allow taking into account nonlinear effects without the ...

Formulating State Space Models in R with Focus on Longitudinal Regression Models [PDF]

open access: yesJournal of Statistical Software, 2006
We provide a language for formulating a range of state space models with response densities within the exponential family. The described methodology is implemented in the R-package sspir. A state space model is specified similarly to a generalized linear
