 Pythagorean expectation - Wikipedia, the free encyclopedia
It is important to keep in mind that Pythagorean estimation is an empirical observation that correlates with winning percentage.
Teams that win a lot of games tend to be underrepresented by the formula (meaning they "should" have won less), and teams that lose a lot of games tend to be overrepresented (they "should" have won more).
Applying the pythagorean expectation to Football: Includes a discussion of how the exponent in the formula should be larger the larger the number of points scored per game becomes.

 Pythagorean expectation   (Site not responding. Last check: 2007-10-09)
Pythagorean expectation is a formula invented by Bill James to estimate how many games a baseball team "should" have won based on the number ofruns they scored and allowed.
The term is derived from the formula's resemblance to Pythagoras ' formula to compute the length of the hypotenuse of a triangle from the lengths of its other two sides.

The Pythagorean Method for relating points scored and allowed to wins and losses is an approximation to a more theoretically correct method, called the Correlated Gaussian Method.
The Pythagorean 16.5 Method was derived from the corresponding method in baseball used by Bill James.
My expectations were for something between 13 and 20, so 16.76 was originally rounded up to 17 and tested as a valid possibility.

 Encyclopedia: Win shares   (Site not responding. Last check: 2007-10-09)
One criticism of this metric is that players who play for teams that win more games than expected, based on the Pythagorean expectation, receive more win shares than players whose team wins fewer games than expected.
Since a team exceeding or falling short of its Pythagorean expectation is generally acknowledged as chance, some believe that credit should not be assigned purely based on team wins.
The Bill James Historical Baseball Abstract, 2001 edition, also written by James, uses win shares to evaluate the careers of many players, and to place them in contexts where they can be compared.

In modern terms the Pythagorean Perspective is that there are not Two Cultures (or many cultures) but One Culture, of which the different arts and sciences are partial expressions.
Windelband (1956) comments that in the Pythagorean society mathematical investigations were pursued for the first time quite independently, and were brought to a high degree of perfection.
The most brilliant achievement of the Pythagoreans was their astronomy far in advance of their contemporaries; the world-all was globular, the single stars luminous globes; the earth a globe moving around the central fire; the distance of the spheres from the central fire depended on simple number relationships.

 THE PYTHAGOREAN PERSPECTIVE: The Arts and Sociobiology
One might attempt to indicate precursor behaviors in other animals which have some structural resemblance to the elaborated forms of the human arts: the numerical and pattern-forming abilities of many animals; the "aesthetic" of peacocks, bowerbirds etc.; the "architectural" capabilities of beavers, bees, termites, birds; the "music appreciation" of gibbons, wolves, whales, and so on.
From its precincts flow the belief in the kinship of all beings; the principles of the brotherhood, of loyalty, modesty, self-discipline, piety and abstinence; a higher view of womanhood, community of property, the parallel between the macrocosm and the microcosm ; the cosmos as an organism; the brain as the locus of the soul.
These techniques would extend to the age-old mysteries of Pythagorean harmonics, to the expressive music of color, to the orchestration of visual rhythms, and, indeed, to every effective and affecting aspect of a work of art.

 12eight :: Pythagorean Differentials: Possible Causes   (Site not responding. Last check: 2007-10-09)
To present this data, and to get a good look at how much deviation there is in the data, I've employed Excel charts, with Pythagorean differentials as the X axis and the variables as the Y axes.
There's maybe a very slight correlation there, but nothing large or certain enough to come to any conclusions about; much of that could be random fluctuation, and the deviation in the data points are simply too large to put any stock in them.
In general, for reasons like this it's difficult to prove the involvement of luck and chance (with negative results in general, you never know for sure why you got it--is it a "true" negative, or was something overlooked?).

 The Orioles Warehouse: Greatest O's: First Basemen
(In truth, the discrepancy should have been even greater, as Texas outperformed its Pythagorean win expectation and Baltimore underperformed its expectation during the relevant years.) Palmeiro also expected to play multiple seasons in Baltimore to close out his career; his current deal is guaranteed only for 2004, but has options for 2005 and 2006.
He was a major reason for the Orioles going from a sub-.500 team to a pennant threat.
But expectations were high after his 1961 season, and he didn't come close to matching that performance in 1962 and 1963, as his power numbers appeared to take a dive (although the raising of the pitcher's mound had a lot to do with that).

To look into this a little bit futher, I've applied a forumula created by famous sabermatician Bill James, called the Pythagorean Expectation, which in my estimation does give a good measure of the expected win/loss percentage for a team in games that it has already played.
Any deviation from this expected win/loss percentage in real life is one way to judge if the team in general is playing to their full capabilities.
According to the Pythagorean Expectation, they should have had a winning percentage of.586, or a record of 25-17.

The main question is how much he would have been bothered by the constant pressure from the owner and the weight of increased expectations.
But in the next three seasons Decinces's bat returned to more ordinary levels, and with a top third-base prospect named Ripken knocking on the door, at the beginning of 1982 the Orioles traded DeCinces and another prospect to the California Angels for outfielder "Disco" Dan Ford.
That move didn't pan out so well, as Ford fell short of expectations, the top third-base prospect instead became an All-Star shortstop, and the team was left with a revolving door at the hot corner for the rest of the decade.
