LOS 8.a: Formulate a multiple regression equation to describe the relation                    READING 9: TIME SERIES ANALYSIS
     between a dependent variable and several independent variables and
     determine the statistical significance  of each independent variable.

                                                                                Answer: the estimated intercept and slope parameters are:
