Generalized linear models are models of the form , where is an invertible function called the link function and the are basis functions of one or more predictor variables. The term is linear in the and is referred to as the linear predictor. The value is the predicted response for the observed response , and the are assumed to be independent observations from the same exponential family of distributions. When the exponential family is the binomial family, the success probability is modeled.
