# The Logistic Function in Regression Analysis¤

The logistic function is commonly used in regression analysis when the response variable is binary, e.g. it only takes the values 0 and 1. Then for any group of individuals with the same explanatory variable values, the fraction of the group whose response variable is 1, can be formed. If this fraction for the ith group is called yi, then the logistic regression equation is:

i.e. the linear regression equation transformed by the logistic function.
