WebLogistic regression is a statistical method for predicting binary classes. The outcome or target variable is dichotomous in nature. Dichotomous means there are only two possible classes. For example, it can be used for cancer detection problems. It computes the probability of an event occurrence. WebIt provides more power by using the sample size of all outcome categories in the likelihood estimation of the parameters and variance, than separate binary logistic regression, which only uses the sample size of the two outcome categories in the likelihood estimation of the parameters and variance. signals and systems simon haykin 2nd editionWebThis analysis is also known as binary logistic regression or simply “logistic regression”.
