A covariance of five ... equation to forecast or predict the variable we desire. Below is the formula for a simple linear regression. The "y" is the value we are trying to forecast, the "b ...

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 ...

Estimating the regression equation by LSE is quite robust to non-normality of and correlation in the errors, but it is sensitive to extreme values of both predictor and predicted. Linear ...
