NettetModern toolkits take away many practical problems experienced with polynomial regression in the past. Theoretically, polynomials can achieve the same ‘perfect’ fit as neural networks, while requiring little more knowledge than basic linear regression. All in all, perhaps it is time to give polynomials a second chance. NettetThe first section in the Prism output for simple linear regression is all about the workings of the model itself. They can be called parameters, estimates, or (as they are above) best-fit values. Keep in mind, parameter estimates could be positive or negative in regression depending on the relationship.
