We use the logistic regression equation to predict the probability of a dependent variable taking the dichotomy values 0 or 1. Suppose x₁, x₂, ..., x_p are the independent variables, α and β_k (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:
