Beta Wavelet - Gnedenko-Kolmogorov Central Limit Theorem Revisited

Gnedenko-Kolmogorov Central Limit Theorem Revisited

Let be a probability density of the random variable, i.e.

, and .

Suppose that all variables are independent.

The mean and the variance of a given random variable are, respectively

.

The mean and variance of are therefore and .

The density of the random variable corresponding to the sum is given by the

Central Limit Theorem for distributions of compact support (Gnedenko and Kolmogorov) .

Let be distributions such that .

Let, and .

Without loss of generality assume that and .

The random variable holds, as,

where and

Famous quotes containing the words central, limit, theorem and/or revisited:

    The best laws cannot make a constitution work in spite of morals; morals can turn the worst laws to advantage. That is a commonplace truth, but one to which my studies are always bringing me back. It is the central point in my conception. I see it at the end of all my reflections.
    Alexis de Tocqueville (1805–1859)

    We live in oppressive times. We have, as a nation, become our own thought police; but instead of calling the process by which we limit our expression of dissent and wonder “censorship,” we call it “concern for commercial viability.”
    David Mamet (b. 1947)

    To insure the adoration of a theorem for any length of time, faith is not enough, a police force is needed as well.
    Albert Camus (1913–1960)

    And yet we constantly reclaim some part of that primal spontaneity through the youngest among us, not only through their sorrow and anger but simply through everyday discoveries, life unwrapped. To see a child touch the piano keys for the first time, to watch a small body slice through the surface of the water in a clean dive, is to experience the shock, not of the new, but of the familiar revisited as though it were strange and wonderful.
    Anna Quindlen (b. 1952)
