Plotting Differences among LSMEANS in Generalized Linear Models
نویسنده
چکیده
The effectiveness of visual interpretation of the differences between pairs of LsMeans in a generalized linear model includes the graph's ability to display four inferential and two perceptual tasks. Among the types of graphs which display some or all of these tasks are the forest plot, the mean-mean scatter plot (diffogram), and the mean-mean multiple comparison (MMC) plot. These graphs provide essential visual perspectives for interpretation of the differences among pairs of LsMeans from a Generalized Linear Model (GLM). The diffogram is a graphical option now available through ODS statistical graphics with linear model procedures such as GLIMMIX of SAS®. Through combining ODS output files of the lsmeans and their differences, the SGPLOT procedure can efficiently produce forest and MMC plots.

Using lsmeans
Least-squares means are predictions from a linear model, or averages thereof. They are useful in the analysis of experimental data for summarizing the effects of factors, and for testing linear contrasts among predictions. The lsmeans package provides a simple way of obtaining least-squares means and contrasts thereof. It supports many models fitted by R core packages (as well as a few key cont...
متن کاملAnalysing interactions of fitted models
This vignette presents a brief review about the existing approaches for the post-hoc analysis of interactions in factorial experiments, and describes how to perform some of the cited calculations and tests with the functions of the package phia in R. Those functions include the calculation and plotting of cell means, and testing simple effects, residual effects, and interaction contrasts, among...
متن کاملSUGI 28: Estimating Standard Errors for CLASS Variables in Generalized Linear Models Using PROC IML
Analysts who work frequently with linear models using the SAS System often use the LSMEANS statement in PROC GLM or PROC MIXED to obtain “adjusted means.” The absence of a clear analogue to these least-squares means for nonlinear or generalized linear models can be an obstacle for both the analyst and the eventual audience of the analysis. This paper shows how to use PROC IML to estimate standa...
متن کاملThe Negative Binomial Distribution Efficiency in Finite Mixture of Semi-parametric Generalized Linear Models
Introduction Selection the appropriate statistical model for the response variable is one of the most important problem in the finite mixture of generalized linear models. One of the distributions which it has a problem in a finite mixture of semi-parametric generalized statistical models, is the Poisson distribution. In this paper, to overcome over dispersion and computational burden, finite ...
متن کاملParameter 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...
