Here is one (it was hard to find) WilliamKF 01:12, 27 March 2006 (UTC):

The formula comes from Voros McCracken via Jay Jaffe (jay at futilityinfielder dot com).
I think we can give $H exactly rather than estimate it:
- $H = H / (BFP - (HR + K + BB + HB)))

It seems this formula rewards the pitcher with a lower dERA whenever there is an error by his teammates (i.e. batter gets to first on a fielding error.) Does that make sense, I would think it should be neutral? WilliamKF 15:41, 6 June 2006 (UTC)
- I guess this is right since reaching first on error counts as an out in your batting average, so it should count positively for the pitcher. WilliamKF 00:01, 16 April 2007 (UTC)
In the text, I've added a link to McCracken's article on dERA, which was also archived by Jay Jaffe: http://www.futilityinfielder.com/dips2.html Mack2 02:05, 21 June 2006 (UTC)
