I'm currently experimenting with different regression techniques on this data set that I have, and I some sources state a method called "polynomial regression". I looked it up and I can't really find any clear explanation of what it is exactly. It sounds quite similar to linear regression - can anyone tell me the difference (if any)?

Polynomial regression is a form of linear regression where higher order powers (2nd, 3rd or higher) of an independent variable are included.
