Uniformly Most Powerful Test - Setting

Setting

Let denote a random vector (corresponding to the measurements), taken from a parametrized family of probability density functions or probability mass functions, which depends on the unknown deterministic parameter . The parameter space is partitioned into two disjoint sets and . Let denote the hypothesis that, and let denote the hypothesis that . The binary test of hypotheses is performed using a test function .

\phi(x) =
\begin{cases}
1 & \text{if } x \in R \\
0 & \text{if } x \in A
\end{cases}

meaning that is in force if the measurement and that is in force if the measurement . Note that is a disjoint covering of the measurement space.

Famous quotes containing the word setting:

    May we two stand,
    When we are dead, beyond the setting suns,
    A little from other shades apart,
    With mingling hair, and play upon one lute.
    William Butler Yeats (1865–1939)

    A happy marriage perhaps represents the ideal of human relationship—a setting in which each partner, while acknowledging the need of the other, feels free to be what he or she by nature is: a relationship in which instinct as well as intellect can find expression; in which giving and taking are equal; in which each accepts the other, and I confronts Thou.
    Anthony Storr (b. 1920)

    Like plowing, housework makes the ground ready for the germination of family life. The kids will not invite a teacher home if beer cans litter the living room. The family isn’t likely to have breakfast together if somebody didn’t remember to buy eggs, milk, or muffins. Housework maintains an orderly setting in which family life can flourish.
    Letty Cottin Pogrebin (20th century)
