Consider a model with features x1, x2, x3 … xn. Let the binary output be denoted by Y, that can take the values 0 or 1. Let p be the probability of Y = 1, we can denote it as p = P (Y=1). Here the term p/ (1−p) is known as the odds and denotes the likelihood of the event taking place.

Logistic Regression for Machine Learning

Witryna5 cze 2024 · For example, let’s bet that a six will come up for a toss of a fair six-sided die. The probability of it happening is 1/6. So the odds in favor of us winning are (1/6) / (5/6) = 1/5 or 1:5. Or the odds of us losing are (5/6) / (1/6) = 5:1. The odds are clearly against us winning.
