Alright here's where I'd like to keep strictly formulas. Anyone can feel free to post here and ill edit this first post with more formulas that you guys add into the thread, i dont have much right now but im sure you guys will have no problem adding to the list... (When posting formulas please also define the variables as well so i can continue to update that list)
Formula List:
On-base percentage (OBP) = (H + BB + HBP) / (AB + BB + HBP + SF)
Slugging percentage (SLG) = (1B) + (2B X 2) + (3B X 3) + (HR X 4) / ABs
OPS = OBP + SLG
wOBA = (0.72xNIBB + 0.75xHBP + 0.90x1B + 0.92xRBOE + 1.24x2B + 1.56x3B +1.95xHR) / PA
IsoP = SLG - AVG
Gross Production Average = (1.8 * OBP + SLG) / 4
Gross Production Average Runs = PA * 1.356 * (GPA ^ 1.77)
BABIP = (H-HR) / (AB-K-HR+SF)
Base Runs (Hitters) = A * (B / (B + C)) + D
Where
A = H + BB + HBP - HR - .5*IBB
B = (1.4*TB - .6*H - 3*HR + .1*(BB + HBP - IBB) + .9*(SB - CS - DP))*1.1
C = AB - H + CS + DP
D = HR
Base Runs (Pitchers) = A * (B / (B + C)) + D
Where
A = H + BB - HR
B = (1.4*(1.12*H + 4*HR) - .6*H - 3*HR + .1*BB)*1.1
C = 3*IP
D = HR
Seamhead's Calculating WAR Thread
WAR for Pitchers
WAR for Position Players
Where...
H = Hit
BB = Base on Balls (Walks)
HBP = Hit by Pitch
AB = At Bats
SF = Sacrifice Flys
TB = Total Bases
K = Strikeout
1B = Singles
2B = Doubles
3B = Triples
HR = Homerun
PA = Plate Appearances
NIBB = Non Intentional Base on Balls
RBOE = Reached Base on Error
GPA = Gross Production Average
