Better Defense Through Bruising - Linear Regression

. Linear Regression

Take SOrate, BBrate, HBPrate, MPrate for all pitchers

 SOrate  BBrate  HBrate  MPrate
  19.69    5.41    0.67  1.73
  13.46    7.65    0.39  1.25
  11.37    9.51    0.93  2.54
   ...      ...     ...   ...
  26.03   10.14    0.09  1.84
  14.05    7.36    0.78  1.16
   9.53    8.43    0.67  2.27

Find the (linear) equation that best matches the data

C₁ * SOrate + C₂ * BBrate + C₃ * HBPrate + K = avg MPrate

Using linear regression, find a formula
