Stability (probability) - Stability in Probability Theory

Stability in Probability Theory

There are a number of mathematical results that can be derived for distributions which have the stability property. That is, all possible families of distributions which have the property of being closed under convolution are being considered. It is convenient here to call these stable distributions, without meaning specifically the distribution described in the article named stable distribution, or to say that a distribution is stable if it is assumed that it has the stability property. The following results can be obtained for univariate distributions which are stable.

  • Stable distributions are always infinitely divisible.
  • All stable distributions are absolutely continuous.
  • All stable distributions are unimodal.

Famous quotes containing the words stability, probability and/or theory:

    ...I feel anxious for the fate of our monarchy, or democracy, or whatever is to take place. I soon get lost in a labyrinth of perplexities; but, whatever occurs, may justice and righteousness be the stability of our times, and order arise out of confusion. Great difficulties may be surmounted by patience and perseverance.
    Abigail Adams (1744–1818)

    Liberty is a blessing so inestimable, that, wherever there appears any probability of recovering it, a nation may willingly run many hazards, and ought not even to repine at the greatest effusion of blood or dissipation of treasure.
    David Hume (1711–1776)

    The great tragedy of science—the slaying of a beautiful theory by an ugly fact.
    Thomas Henry Huxley (1825–1895)
