WebThe function g ( μ i) will be called the link\/ function. Examples of link functions include the identity, log, reciprocal, logit and probit. We further assume that the transformed mean follows a linear model, so that (B.5) η i = x i ′ β. The quantity η i is called the linear predictor . Note that the model for η i is pleasantly simple. http://www.imm.dtu.dk/~hmad/GLM/Slides_2012/week08/lect08a.pdf dutch chip making machineWebNov 15, 2024 · For example, in Logistic Regression the Sigmoid Function scales the output to be in-between 0 and 1. In fact Logisitic Regression is based on the Binomial distribution which is also part of the exponential family, hence a GLM. For Linear Regression, the link function is the identity function and so it does not transform the linear predictors. eastern carryout owings mills
