uations of Eight Articles Using Logistic Regression, and (5) Summary. Logistic Regression Models The central mathematical concept that underlies logistic regression is the logit—the natural logarithm of an odds ratio. The simplest example of a logit derives from a 2 ×2 contingency table. Consider an instance in which the distri-

Binary Logistic Regression • The logistic regression model is simply a non-linear transformation of the linear regression. • The logistic distribution is an S-shaped distribution function (cumulative density function) which is similar to the standard normal distribution and constrains the estimated probabilities to lie between 0 and 1. 9

Introduction to Binary Logistic Regression 3 Introduction to the mathematics of logistic regression Logistic regression forms this model by creating a new dependent variable, the logit(P). If P is the probability of a 1 at for given value of X, the odds of a 1 vs. a 0 at any value for X are P/(1-P). The logit(P)

Logistic regression has been especially popular with medical research in which the dependent variable is whether or not a patient has a disease. For a logistic regression, the predicted dependent variable is a function of the probability that a particular subject will be in one of the categories (for example, the probability that Suzie Cue has the

About Logistic Regression It uses a maximum likelihood estimation rather than the least squares estimation used in traditional multiple regression. The general form of the distribution is assumed. Starting values of the estimated parameters are used and the likelihood that the sample came from a population with those parameters is computed.
