Logistic regression is a statistical
Logistic regression is a statistical model that predicts the probability that a random variable belongs to a certain category or class.

After that we form our likelihood function as a Bernoulli distribution given a data set, and using the maximum likelihood estimation method the model parameters are estimated using the gradient ascent algorithm.
