WebA logistic regression model allows us to establish a relationship between a binary outcome variable and a group of predictor variables. It models the logit-transformed probability as a linear relationship with the predictor variables. WebThe response variable Y is a binomial random variable with a single trial and success probability π. Thus, Y = 1 corresponds to "success" and occurs with probability π, and Y = 0 corresponds to "failure" and occurs with probability 1 − π. The set of predictor or explanatory variables x = ( x 1, x 2, …, x k) are fixed (not random) and can ...
