I had an email today from Matt Hergott, who wrote:
"I notice you place an emphasis on charts and graphs. Many analyses could be helped by your suggestion that software offer charts of the data before running a regression. Along these lines, you might want to look at my new website: www.artemis-econometrics.com .
It contains four interactive three-dimensional scenes pertaining to econometrics and finance. The first graph is a simulation that makes it easy to spot outliers in a regression with two explanatory variables. The 3-D interactivity is important because people generally need different perspectives to see where the residuals are located.
It looks as if there are exciting times ahead!
