Glm versus linear regression
Did you know?
In statistics, a generalized linear model (GLM) is a flexible generalization of ordinary linear regression. The GLM generalizes linear regression by allowing the linear model to be related to the response variable via a link function and by allowing the magnitude of the variance of each measurement to be a function of its predicted value. Generalized linear models were formulated by John Nelder and Robert Wedderburn as a way of u… WebMore on GLM families. A GLM is linear model for a response variable whose conditional distribution belongs to a one-dimensional exponential family. Apart from Gaussian, Poisson and binomial families, there are other interesting members of this family, e.g. Gamma, inverse Gaussian, negative binomial, to name a few. ...
