Note that “die” is a dichotomous variable because it has only 2 possible outcomes (yes or no). Logistic regression is the appropriate regression analysis to conduct when the dependent variable is dichotomous (binary).

Example: Spam or Not. 2. The logistic regression coefficients give the change in the log odds of the outcome for a one unit increase in the predictor variable. For every one unit change in gre, the log odds of admission (versus non-admission) increases by 0.002. For a one unit increase in gpa, the log odds of being admitted to graduate school increases by 0.804.

Applications. Logistic regression is used in various fields, including machine learning, most medical fields, and social sciences. For example, the Trauma and Injury Severity Score (), which is widely used to predict mortality in injured patients, was originally developed by Boyd et al. using logistic regression.Many other medical scales used to assess severity of a patient have been developed

Logistic regression analysis is a popular and widely used analysis that is similar to linear regression analysis except that the outcome is dichotomous (e.g., success/failure or yes/no or died/lived). 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. Types of Logistic Regression. 1. Binary Logistic Regression. The categorical response has only two 2 possible outcomes.
