Regression analysis is a powerful statistical technique that identifies the association between two or more quantitative variables: a dependent variable, whose value is to be predicted, and regressikn independent or explanatory variable or variablesabout which significant amount of knowledge is available. This statistical tool is used to develop the equation that represents the relationship between the variables.

A simple regression analysis can show that the relation between an independent variable and a dependent variable is linear, using the simple linear regression equation. Multiple regression analysis provides an equation that predicts dependent variable from two or more independent variables. In other words, it can be said that multiple regression involves a single what is a nonlinear function table variable and two or more independent variables, while simple regression model involves one dependent variable and one independent variable.

Regression analysis is concerned with the nature as well as the degree of association between variables. Although the independent variables what does simple linear regression analysis tell you explain the variation in the dependent variable, it does not necessarily imply causation.
