Regression Analysis (conclusion)
There are three ways to report regression results: in a table, as an equation with standard errors in parentheses, and as an equation with t ratios in parentheses.
Multiple regression is closely connected to the idea (common in economics) of showing the effects of changing one variable while holding other variables constant. Here we see that beta is the slope of the demand curve, and gamma is the shift that occurs when ads changes by one unit.
Other than a new formula for the degrees of freedom, constructing a confidence interval is a familiar process.
