Regression analysis is a statistical method of determining the mathematical functional relationship connecting independent variable and a dependent variable. Based on the kind of relationship between the dependent variable and the set of independent variable, there arises two broad categories of regression, linear regression and non-linear regression. If the relationship is linear and there is only one independent variable, then the regression is called as simple linear regression. On the other hand, if the relationship is linear and the number of independent variables is two or more, then the regression is called as multiple linear regression. If the relationship between the dependent variable and the independent variable is not linear, then the regression is called as non-linear regression.
