Create a set of data on 10 cases that illustrates leverage, distance, and influence. Use any standard regression program to produce statistics measuring these attributes.

Produce a set of data where the variance of Y values associated with large values of X is greater than the variance of Y values associated with small values of X. Then run the regression and plot the residuals on the ordinate against X on the abscissa. What pattern emerges?
