NettetLogistic regression is a special case of the generalized linear regression where the response variable follows the logit function. The input of the logit function is a probability p, between 0 and 1. The odds ratio for probability p is defined as p/ (1-p), and the logit function is defined as the logarithm of the Odds ratio or log-odds. NettetThe F-Test for Regression Analysis. The F-test, when used for regression analysis, lets you compare two competing regression models in their ability to “explain” the variance in the dependent variable. The F-test is used primarily in ANOVA and in regression analysis. We’ll study its use in linear regression.
