Logarithmic Link Function at Mamie Jeanne blog

Logarithmic Link Function. Here are two versions of the same basic model equation for count data: A natural fit for count variables that follow the poisson or negative binomial distribution is the log link. I think there is a sort of beautiful elegance in the maths of how the link function works. Ln(μ) = β 0 + β 1 x. It does not log transform the outcome variable. The logit link function is a fairly simple transformation of the prediction curve and also provides odds ratios, both features that make it. The link function should reflect the relationship between the linear predictors and the response scale. A generalized linear model (glm) generalizes normal linear regression models in the following directions. Understanding this theory will also help you build better models for your data and interpret them in more nuanced ways. For example, use a logit link for probabilities in a binomial model or a log link for count data in a poisson model. More specifically, it connects the predictors in a model with the expected value of the response (dependent) variable in a linear way. Μ = exp(β 0 + β 1 x), also written as μ. The log link exponentiates the linear predictors.
