xRBI
I can’t tell if this is FanGraphs or NotGraphs or even RotoGraphs material, so I’ll just say safe and put it here. My formula for expected RBI, supposedly a pretty simple stat:
xRBI = position-regressed indexed clutch score * league-indexed contact rate * position-indexed isolated power * health-adjusted and lineup-slot-indexed plate appearances * expected team OBP * projected raw plate appearances
I’m pretty sure I got something wrong.
