Bayesian Logistic Regression. These aren’t really different types of regression models per se. This is a mix of different techniques with different characteristics, all of which can be used for linear regression, logistic regression or any other kind of generalized linear model. Linear and logistic are the only two types of base models covered., whether these assumptions are being violated. Given that logistic and linear regression techniques are two of the most popular types of regression models utilized today, these are the are the ones that will be covered in this paper.

The model for logistic regression analysis, described below, is a more realistic representation of the situation when an outcome variable is categorical. The model for logistic regression analysis assumes that the outcome variable, Y, is categorical (e.g., dichotomous), but LRA does not model this outcome variable directly. Rather, LRA is based Logistic regression model is the most popular model for binary data. Logistic regression model is generally used to study the relationship between a binary response variable and a group of predictors (can be either continuousand a group of predictors (can be either continuous or categorical).

    This justifies the name ‘logistic regression’. Data is fit into linear regression model, which then be acted upon by a logistic function predicting the target categorical dependent variable.
