In baseball statistics, defense-independent ERA (dERA) is a statistic that projects what a pitcher's earned run average (ERA) would have been, if not for the effects of defense and luck on the actual games in which he pitched.
[1][2][page needed] Version 2.0 of dERA uses the following statistics:
0) Multiply BFP by .0074 to get the number of intentional walks allowed (dIBB).
2) Divide (BB-IBB) by (BFP-IBB-HB), and call this number $BB.
6) Estimate hits per balls in the field of play ($H): 7) To get the projected number of Hits Allowed (DIPS 'Hits Allowed', or dH), multiply $H by the number of balls hit in the field of play (BHFP).
