+# -*- coding: utf-8 -*-%0A%22%22%22Polynomial regression for machine learning.%0A%0Apolynomial regression is a form of regression analysis in which the%0Arelationship between the independent variable x and the dependent variable y is%0Amodelled as an nth degree polynomial in x. Polynomial regression fits a%0Anonlinear relationship between the value of x and the corresponding conditional%0Amean of y, denoted E(y %7Cx)Although polynomial regression fits a nonlinear model%0Ato the data, as a statistical estimation problem it is linear, in the sense%0Athat the regression function E(y %7C x) is linear in the unknown parameters that%0Aare estimated from the data. For this reason, polynomial regression is%0Aconsidered to be a special case of multiple linear regression.%0A%0AExample:%0A%0A        $ python regularPolynomialRegression.py%0A%0ATodo:%0A    *%0A%22%22%22%0A
