1. Overview If a regression assumption is violated, performing regression analysis will yield an incorrect result. The linear regression is the simplest non-trivial relationship. 2. Linearity $$\gamma =\beta_{0}+\beta_{1}x_{1}+\beta_{2}x_{2}+\cdots +\beta_{k}x_{k}+\varepsilon $$ How can you verify if the relationship between two variables is linear The easiest way is to choose an independent var..
