Understand the basic ideas behind modeling categorical data with binary logistic regression understand how to fit the model and interpret the parameter estimates. Logistic regression is a method for fitting a regression curve, y = f(x), when y is a categorical variable the typical use of this model is predicting y given a set.

Logistic (or logit) regression is a modeling technique: for any given x, the logit model provides the value for the observation that can be used with the logistic. Logistic regression what is the logistic curve what is the base of the natural logarithm why do statisticians prefer logistic regression to ordinary linear. Logistic regression is a simple classification algorithm for learning to make such decisions in linear regression we tried to predict the value of y^{(i). Logistic regression is a machine learning classification algorithm that is used to predict the probability of a categorical dependent variable in logistic regression. Why use logistic regression there are many important research topics for which the dependent variable is limited (discrete not continuous.
