Generalized linear model with log link
WebA link function in a Generalized Linear Model maps a non-linear relationship to a linear one, which means you can fit a linear model to the data. More specifically, it connects the predictors in a model with the expected value of the … WebIn R, a family specifies the variance and link functions which are used in the model fit. As an example the “poisson” family uses the “log” link function and “ μ μ ” as the variance …

WebJun 7, 2015 · 2 Answers. I would suggest using a generalised linear model (GLM) with a log-link function instead of directly log-transforming your variables; in R you can simply use glm with family= gaussian (link='log') to begin with.
