Document Summary
It can also be used to tell you how of the variance in the dependent variable is explained by the predictor variable(s): regression, particularly multiple regression, is being used more and more in. Analytics research that affects many aspects of our daily lives, from how much we pay for automobile insurance to which adds appear in our social media: there are many kinds of regression techniques. In this chapter, we focus on simple linear regression with two variables and a brief introduction to multiple linear regression. Here is the formula for calculating the predicted value of y for a given value of x: Multiple regression: another powerful regression technique is called multiple regression, in a multiple regression, one dependent variable is predicted by multiple independent (i. e. , predictor) variables. Here is what the regression equation looks like with two independent variables:
