A pitchers game score for each start is calculated with: gameScore = 47.4 + strikeouts + {(outs*1.5)} {(walks*2)} {(hits*2)} {(runs*3)} {(homeruns*4). Since the fielding-independent statistics that FIP uses in its formula (strikeouts, home runs, walks, hit batsmen) tend to stay more constant year to year than ERA, FIP tends to be consistent than ERA year to year. This constant would work like the exponent 2 works for each year in Jamess formula. 30 0 obj Building a sports betting model can be difficult work. (RPGF home + RPGA road - RPG la) + (RPGF road + RPGA home - RPG la) Method 1.
