Web6 Mar 2024 · The basis can be created in R using function poly (x,3) with inputs x (referring to the variable), and p (referring to the degree of the polynomial). This leads to a simple univariate smooth model of the form: yi = f ( xi )+ ε where f () is some function/transformation of the predictor. WebThe general idea of smoothing is to group data points into strata in which the value of f (x) f ( x) can be assumed to be constant. We can make this assumption because we think f (x) …
