Logistic Regression

fractal-12h We use the logistic regression equation to predict the probability of a dependent variable taking the dichotomy values 0 or 1. Suppose x1, x2, ..., xp are the independent variables, α and βk (k = 1, 2, ..., p) are the parameters, and E(y) is the expected value of the dependent variable y, then the logistic regression equation is:

                 ∑
E (y) = 1∕(1 +e- (α+  kβkxk))
