Using Plate Discipline To Estimate Walk & Strikeout Rate: Corrected

For a while, I have wondered if pitch data could be used to estimate a player's walk and strikeout rates. At Fangraphs.com, they display the percentage rate for pitches swung at and hit inside and outside the strike zone for each player (O-Swing%,Z-SWing%,O-Contact%,Z-Contact%). Using multiple variate regression, I took the 4 variables (outside swing and miss, outside contact, strike zone swing and miss, strike zone contact) and compared them to strikeout and walk percentages.
