What is the GLM procedure?

The GLM Procedure. Overview. The GLM procedure uses the method of least squares to ?t general linear models. Among the statistical methods available in PROC GLM are regression, analysis of variance, analysis of covariance, multivariate analysis of variance, and partial corre- lation.

Can GLM fit generalized linear models?

glm ?ts generalized linear models. It can ?t models by using eitherIRLS(maximum quasilikelihood) or Newton–Raphson (maximum likelihood) optimization, which is the default. See[U] 27 Overview of Stata estimation commandsfor a description of all of Stata’s estimation commands, several of which ?t models that can also be ?t using glm. Quick start

How do we interpret a GLM?

It is essential to stress that even though we speak of “dependency”, “explana-tions” and “e?ects,”causal interpretationof a GLM depends on the design ofthe study. True experiments (i.e., direct experimental manipulation, randomassignment, and strict control) permit inferences about causality.

What is GLM in Stata?

glm— Generalized linear models 9 4. Family negative binomial, log-link models—also known as negative binomial regression models—are used for data with an overdispersed Poisson distribution. Although glm can be used to ?t such models, using Stata’s maximum likelihood nbreg command is probably better. In theGLMapproach, you specify family(nbinomial #
