WebThe logit in logistic regression is a special case of a link function in a generalized linear model: it is the canonical link function for the Bernoulli distribution. The logit function is the negative of the derivative of the binary entropy function. The logit is also central to the probabilistic Rasch model for measurement, which has ...

Introduction to Binary Logistic Regression

WebPlease note that when we speak of logistic regression, we really mean binary logistic regression, as opposed to ordinal logistic regression or multinomial logistic regression. A binary variable refers to a variable that is coded as 0, 1 or missing; it cannot take on any value other than those three.

"WebFor binary logistic regression, the format of the data affects the deviance R 2 value. The deviance R 2 is usually higher for data in Event/Trial format. Deviance R 2 values are comparable only between models that use the same data format. Goodness-of-fit statistics are just one measure of how well the model fits the data.
