Probability Distribution Function

Depending upon which text is consulted, a probability distribution function is any of:

  • a probability distribution function,
  • a cumulative distribution function,
  • a probability mass function, or
  • a probability density function.

The similar term probability function may mean any of the above and, in addition,

  • a probability measure function, as in a probability space, where the domain of the function is the set of events.

Famous quotes containing the words probability, distribution and/or function:

    Legends of prediction are common throughout the whole Household of Man. Gods speak, spirits speak, computers speak. Oracular ambiguity or statistical probability provides loopholes, and discrepancies are expunged by Faith.
    Ursula K. Le Guin (b. 1929)

    My topic for Army reunions ... this summer: How to prepare for war in time of peace. Not by fortifications, by navies, or by standing armies. But by policies which will add to the happiness and the comfort of all our people and which will tend to the distribution of intelligence [and] wealth equally among all. Our strength is a contented and intelligent community.
    Rutherford Birchard Hayes (1822–1893)

    As a medium of exchange,... worrying regulates intimacy, and it is often an appropriate response to ordinary demands that begin to feel excessive. But from a modernized Freudian view, worrying—as a reflex response to demand—never puts the self or the objects of its interest into question, and that is precisely its function in psychic life. It domesticates self-doubt.
    Adam Phillips, British child psychoanalyst. “Worrying and Its Discontents,” in On Kissing, Tickling, and Being Bored, p. 58, Harvard University Press (1993)
