Ratio Distributions in Multivariate Analysis

Ratio distributions also appear in multivariate analysis. If the random matrices X and Y follow a Wishart distribution then the ratio of the determinants

is proportional to the product of independent F random variables. In the case where X and Y are from independent standardized Wishart distributions then the ratio

has a Wilks' lambda distribution.

Famous quotes containing the words ratio and/or analysis:

    Official dignity tends to increase in inverse ratio to the importance of the country in which the office is held.
    Aldous Huxley (1894–1963)

    Analysis as an instrument of enlightenment and civilization is good, in so far as it shatters absurd convictions, acts as a solvent upon natural prejudices, and undermines authority; good, in other words, in that it sets free, refines, humanizes, makes slaves ripe for freedom. But it is bad, very bad, in so far as it stands in the way of action, cannot shape the vital forces, maims life at its roots. Analysis can be a very unappetizing affair, as much so as death.
    Thomas Mann (1875–1955)
