Logistic Regression

If the matter of interest is not “how much” but “either/or,” then logistic regression is the way to go. Logistic regression produces similar answers to OLS regression, but is designed specifically to provide the “why’s” behind “yes/no,” “bought it/didn’t buy it,” “used it/didn’t use it,” and any other matters that involve a choice between two alternatives. An added bonus of logistic regression is that it allows for presentation of results using easy-to-understand probability estimates.
