How do you do a simple linear regression?
The formula for a simple linear regression is:y is the predicted value of the dependent variable (y) for any given value of the independent variable (x).B0 is the intercept, the predicted value of y when the x is 0.B1 is the regression coefficient – how much we expect y to change as x increases.More items…•.

Multiple regression requires two or more predictor variables, and this is why it is called multiple regression. The multiple regression equation explained above takes the following form: y = b1x1 + b2x2 + … + bnxn + c.
