Like correlation, linear regression can only reflect a straight-line relationship between variables. If your variables have some other kind of relationship, you should not use linear regression to talk about them. NettetThere are three basic definitions for integral linearity in common use: independent linearity, zero-based linearity, and terminal, or end-point, linearity. In each case, …
