Polynomial Regression and Transformations

Polynomial Regression and Transformations. STA 671 Summer 2008. Review. The estimated residuals e 1 ,…,e n provide the best method for checking the assumptions. Remember the residuals ε i ~ N(0, σ ). The estimated residuals should be close to that.

Multiple Linear Regression

Multiple Linear Regression. Polynomial Regression. Monotonic but Non-Linear. The relationship between X and Y may be monotonic but not linear. The linear model can be tweaked to take this into account by applying a monotonic transformation to Y, X, or both X and Y.
