Alternate Formulae
Each of the following formula's use innings pitched(IP), a measure of the number of outs a team made while a pitcher was in the game. Since most outs rely on fielding, the results from calculations using innings pitched are not truly independent of team defense. While the creators of DICE, FIP and similar statistics all suggest they are "defense independent", others have pointed out that their formulas involve innings pitched(IP). Innings pitched is a statistical measure of how many outs were made while a pitcher was pitching. This includes those made by fielders who are typically involved in more than two thirds of the outs. These critics claim this makes pitchers' DICE or FIP highly dependent on the defensive play of their fielders.

Famous quotes containing the words alternate and/or formulae:
“It might become a wheel spoked red and white
In alternate stripes converging at a point
Of flame on the line, with a second wheel below,
Just rising, accompanying, arranged to cross,
Through weltering illuminations, humps
Of billows, downward, toward the drift-fire shore.”
—Wallace Stevens (1879–1955)
“I don’t believe in providence and fate, as a technologist I am used to reckoning with the formulae of probability.”
—Max Frisch (1911–1991)
