Dave Studeman of The Hardball Times derived Expected Fielding Independent Pitching (xFIP), a regressed version of FIP. Calculated like FIP, it differs in that it normalizes the number of home runs the pitcher allows, replacing a pitcher's actual home run total with an expected home run total (xHR).
The formula uses a player's standard deviations from the mean (a weighted z-score [9]) of the DIPS statistic xFIP (expected Fielding Independent Pitching), swinging strike percentage, overall strike percentage, and the differential between the pitcher's ERA and xFIP to determine a quantitative value for each pitcher.
Wins above replacement or wins above replacement player, commonly abbreviated to WAR or WARP, is a non-standardized sabermetric baseball statistic developed to sum up "a player's total contributions to his team". [1]
xFIP: This variant substitutes a pitcher's own home run percentage with the league average; G – Games (AKA "appearances"): number of times a pitcher pitches in a season; GF – Games finished: number of games pitched where player was the final pitcher for their team as a relief pitcher
Similar to FIP, tRA uses a mathematical formula to isolate the pitcher from his defense. Thus, tRA is a defense-independent pitching statistic . Unlike FIP and dERA , however, tRA takes into account batted ball type (that is, line drives, fly balls, pop ups, and ground balls) as well as strikeouts, walks, and home runs.
In mathematics, Machin-like formulas are a popular technique for computing π (the ratio of the circumference to the diameter of a circle) to a large number of digits.They are generalizations of John Machin's formula from 1706:
The original use of interpolation polynomials was to approximate values of important transcendental functions such as natural logarithm and trigonometric functions.Starting with a few accurately computed data points, the corresponding interpolation polynomial will approximate the function at an arbitrary nearby point.
The superformula is a generalization of the superellipse and was proposed by Johan Gielis in 2003. [1] Gielis suggested that the formula can be used to describe many complex shapes and curves that are found in nature.
