Bias With Respect To Other Loss Functions
Any mean-unbiased minimum-variance estimator minimizes the risk (expected loss) with respect to the squared-error loss function, as observed by Gauss. A median-unbiased estimator minimizes the risk with respect to the absolute loss function, as observed by Laplace. Other loss functions are used in statistical theory, particularly in robust statistics.

Famous quotes containing the words bias, respect, loss and/or functions:
“The solar system has no anxiety about its reputation, and the credit of truth and honesty is as safe; nor have I any fear that a skeptical bias can be given by leaning hard on the sides of fate, of practical power, or of trade, which the doctrine of Faith cannot down-weigh.”
—Ralph Waldo Emerson (1803–1882)
“If there is one realm in which it is essential to be sublime, it is in wickedness. You spit on a petty thief, but you can’t deny a kind of respect for the great criminal.”
—Denis Diderot (1713–1784)
“Upset at the young wife’s
first loss of virtue
in a riverside thicket,
a flock of birds
flies up,
mourning the loss
with their wings.”
—Hla Stavhana (c. 50 A.D.)
“One of the most highly valued functions of used parents these days is to be the villains of their children’s lives, the people the child blames for any shortcomings or disappointments. But if your identity comes from your parents’ failings, then you remain forever a member of the child generation, stuck and unable to move on to an adulthood in which you identify yourself in terms of what you do, not what has been done to you.”
—Frank Pittman (20th century)
