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. http://wise.cgu.edu/wp-content/uploads/2016/07/Introduction-to-Logistic-Regression.pdf

WebLogistic regression typically optimizes the log loss for all the observations on which it is trained, which is the same as optimizing the average cross-entropy in the sample. For example, suppose we have samples with each sample indexed by . The average of the loss function is then given by: where , with the logistic function as before. WebWe will prefer to use GLM to mean "generalized" linear model in this course. There are three components to any GLM: Random Component - specifies the probability distribution of the response variable; e.g., normal distribution for $Y$ in the classical regression model, or binomial distribution for $Y$ in the binary logistic regression model ... on the way lantana
