| '''Defense-Independent ERA''' (dERA), created by ], projects what a pitcher's ] would have been, if not for the effects of defense and luck on the actual games in which he pitched. | |||
| Version 2.0 of dERA uses the following statistics: | |||
| <ul> | |||
| <li>] | |||
| <li>] | |||
| <li>] | |||
| <li>] | |||
| <li>] | |||
| <li>] | |||
| </ul> | |||
| 0) Multiply BFP by .0074 to get the number of intentional walks allowed (dIBB). | |||
| 1) Divide HB by BFP-IBB. Call this $HB. Then multiply $HB by BFP-dIBB. This number gives you the DIPS number of Hit Batsmen (dHB). | |||
| 2) Divide (BB-IBB) by (BFP-IBB-HB), and call this number $BB. Multiply BFP by 0.0074, and call this dIBB. | |||
| 2a) Then multiply $BB by (BFP-dIBB-dHB). Take this number and add IBB. This number is now the DIPS number of total walks allowed (dBB). | |||
| 3) Divide K by (BFP-HB-BB) and call this number $K. Remember this number for later. | |||
| 3a) Multiply $K by (BFP-dBB-dHB). This will give you the DIPS number of strikeouts (dK). | |||
| 4) Divide HR by (BFP-HB-BB-K) and call this number $HR. Remember this number for later. | |||
| 4a) Multiply $HR by (BFP-dBB-dHB-dK). This will give you the DIPS number of Home Runs (dHR). | |||
| 5) Calculate the number of 'Balls Hit in the Field of Play'. This is BFP-dHR-dBB-dK-dHB. | |||
| 6) Now we'll estimate hits per balls in the field of play ($H): | |||
| 6a) Take the number .304396 and subtract .01083 if the pitcher is strictly a Knuckleball pitcher. If not keep the .304396 number. | |||
| 6b) Take the result from the last step and add .002321 if the pitcher is left handed, if not keep the number from the above step. | |||
| 6c) Take the $K figure from above and multiply it by .04782. Subtract this number from the number in 5b. | |||
| 6d) Take the $HR figure from way above and multiply it by .08095. Subtract this number from the number in 5c. | |||
| 6e) Whatever number you now have is your $H figure. | |||
| 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). | |||
| 7a) Add this number to dHR. This number is the DIPS total of Hits Allowed (dH). | |||
| 8) Take BFP-dBB-dHB-dK-dH and multiply that number by 1.048. Add dK to that number. Take that number and divide by 3. This is the DIPS total of Innings Pitched (dIP). | |||
| 9) Sum the following products: | |||
| : (dH-dHR)*.49674 | |||
| : dHR*1.294375 | |||
| : (dBB-dIBB)*.3325 | |||
| : dIBB*.0864336 | |||
| : dK*(-.084691) | |||
| : dHB*.3077 | |||
| : (BFP-dHB-dBB-dK-dH)*(-.082927) | |||
| The sum of all of these is the DIPS total of earned runs (dER). | |||
| 10) Calculate ] as you normally would. (9*dER)/dIP. This is the DIPS ERA (dERA). | |||
