The standard errors for these regression coefficients are very small, and the t statistics are very large (-147 and 50.4, respectively). This produces the finished graph that you can include in your papers: The visualization step for multiple regression is more difficult than for simple regression, because we now have two predictors. lisa robertson local steals and deals today.
