Logistic regression prediction formula
There are various equivalent specifications and interpretations of logistic regression, which fit into different types of more general models, and allow different generalizations. The particular model used by logistic regression, which distinguishes it from standard linear regression and from other types of regression analysis used for binary-valued outcomes, is the way the probability of a particular outcome is linked to the linear predictor function: WitrynaThis Logistic Regression formula can be written generally in a linear equation form as: Where P = Probability of Event, and are the regression coefficients and X1,X2,… are …
