    Formulas Thread

    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

    Son, you just don't get it, i'm talking bout the TWTW!
