dice: Defense-Independent Component ERA

In Sabermetrics: Sabermetrics Functions for Baseball Analytics

Description

DICE represents a way to measure a pitcher's performance on the ERA scale using only events a pitcher can "control"

Usage

dice(hr, bb, hbp, k, ip)

Arguments

hr	Home Runs
bb	Walks
hbp	Hit By Pitches
k	Strikeouts
ip	Innings Pitched

Details

DICE uses the typical ERA scale.

Value

Returns a value equal to (13*hr+3*bb+3*hbp-2*k)/ip + 3.0

Note

Innings Pitched (IP) is commonly reported with .1 indicating 1/3 of an inning and .2 indicating 2/3 of an inning. In order for this function to be accurate, please change the decimal to .333 for 1/3 of an inning and .666 for 2/3 of an inning.
