Binary logistic regression dataset
WebApr 10, 2024 · The goal of logistic regression is to predict the probability of a binary outcome (such as yes/no, true/false, or 1/0) based on input features. The algorithm models this probability using a logistic function, which maps any real-valued input to a value between 0 and 1. Since our prediction has three outcomes “gap up” or gap down” or “no ... WebNov 4, 2015 · Then you'll want to train your logistic regression model using three features. X1 = IsRed? = (1, 0, 0, 0, 1), X2 = IsBlue? = (0, 1, 1, 0, 0), X3 = IsGreen = (0, 0, 0, 1, 0) where 1s represent "yes" or "true" and 0s represent "no" or "false". In other words, you create a binary vector for each unique class (i.e. category). – Nov 3, 2015 at 17:20
