Bias of An Estimator - Bias With Respect To Other Loss Functions

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 being an egomaniac means I believe in what I do and in my art or my music, then in that respect you can call me that.... I believe in what I do, and I’ll say it.
    John Lennon (1940–1980)

    Claudio. The old ornament of his cheek hath already stuffed tennis-balls.
    Leonato. Indeed, he looks younger than he did, by the loss of a beard.
    William Shakespeare (1564–1616)

    In today’s world parents find themselves at the mercy of a society which imposes pressures and priorities that allow neither time nor place for meaningful activities and relations between children and adults, which downgrade the role of parents and the functions of parenthood, and which prevent the parent from doing things he wants to do as a guide, friend, and companion to his children.
    Urie Bronfenbrenner (b. 1917)
