This paper reviews the bias of this modeling, as well as history, purpose, assumptions, and steps. Then the paper follows with Classification of regression analysis in to 8 classes. Specifically, linear and non linear regression is discussed by details. We end the paper with application of regression modeling. We find this paper as a statistical modeling guide for scholars. -- statistical modeling ; linear regression ; non linear regression ; functional relationship
