Some key advantages of linear regression are that it can be used to predict values of the outcome variable and incorporate more than one explanatory variable. The linear regression equation is perhaps ...

A multiple regression formula has multiple slopes (one for each variable) and one y-intercept. It is interpreted the same as a simple linear regression formula—except there are multiple ...

The purpose of this tutorial is to continue our exploration of regression by constructing linear models with two ... because we simply cut-and-paste the equation, delete a variable name, and re-run ...
