I'm not sure that the treadline is appropriate. It is not a very good predictor for the points shown... Maybe even misleading?--Nick Johnson 15:34, 18 April 2007 (CDT)

    • it's just the line of best fit (generated by Excel). Richard Jensen 16:30, 18 April 2007 (CDT)
But its such a bad fit that it's meaningless. Is it a polynomial fit? If so, what order and why? Or, is it an exponential fit? If so, why? IMHO, these things add a lot of meaning to the graph, which you may not have intended. If it's in an article about the new deal, why not fit the treadline to points starting at 1933? It's inappropriate to have such a simple treadline that covers pre-crash, crash, and new deal... This is an example of where a best fit reflects the data very poorly. --Nick Johnson 14:00, 19 April 2007 (CDT)
