In statistics, polynomial regression is a form of regression analysis in which the relationship between the independent variable x and the dependent variable y is modelled as an nth degree polynomial in x. Polynomial regression fits a nonlinear relationship between the value of x and the corresponding conditional mean of y, denoted E(y x). Although polynomial regression fits a nonlinear model to the data, as a statistical estimation problem it is linear, in the sense that the re… Web28 May 2024 · Second order thinking is outside the box thinking.
