Logistic regression probability of default
WitrynaThus, the logistic transformation (log odds) of the probability of default has the features of a linearregression: f(x) = ln p(x) 1 p(x) (2) The coefficients which result from the logistic regression do no have a direct interpretation. The contribution of each variable to the estimated probability can be quantified through the
