NettetThe logistic regression model is an example of a broad class of models known as generalized linear models (GLM). For example, GLMs also include linear regression, ANOVA, poisson regression, etc. Random Component – refers to the probability distribution of the response variable (Y); e.g. binomial distribution for Y in the binary … NettetGeneralized linear model (GLM) is a generalization of ordinary linear regression that allows for response variables that have error distribution models other than a normal distribution like Gaussian distribution.

Results: Out of 1,247 patients, 18%, 13%, and 9% reported experiencing CPSP at 6, 12, and 24 months, respectively. NettetThe generalized linear model expands the general linear model so that the dependent variable is linearly related to the factors and covariates via a specified link function. Moreover, the model allows for the dependent variable to have a non-normal distribution. It covers widely used statistical models,
