Witryna11 lip 2024 · The logistic regression equation is quite similar to the linear regression model. Consider we have a model with one predictor “x” and one Bernoulli response variable “ŷ” and p is the probability of ŷ=1. The linear equation can be written as: p = b 0 +b 1 x --------> eq 1. The right-hand side of the equation (b 0 +b 1 x) is a linear ... Witryna摘要： We present a regularized logistic regression model for evaluating player contributions in hockey. The traditional metric for this purpose is the plus-minus statistic, which allocates a single unit of credit (for or against) to each player on the ice for a goal.
