WebBinary logistic regression models the relationship between a set of predictors and a binary response variable. A binary response has only two possible values, such as win … WebHastie and Tibshirani defines that linear regression is a parametric approach since it assumes a linear functional form of f (X). Non-parametric methods do not explicitly assume the form for f (X). This means that a non-parametric method will fit the model based on an estimate of f, calculated from the model.
