title: A Note On Polynomial Regression.
abstract: The problem of colinearity among the predictors in the polynomial regression model is discussed. It is shown that when X, the independent variable, follows a standard normal distribution the degree of colinearity in the system rapidly increases as a direct function of the polynomial's degree. Some recommendations of Bradley and Srivastava (1979) are reiterated and some possible alternative approaches are suggested.
