In one respect the cross-sectional regressions will be simpler: we do not need to check as to whether the data are in statistical control through time. Web(e) The cautious approach to regression requires that high leverage points be set aside and that the regression should be repeated without these points. Give the regression on the remaining 65 points. Here are two artful ways to omit points from a Minitab regression. Method 1: Start by copying the dependent variable column to a new column. Use
