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:

    should some limb of the devil
    Destroy the view by cutting down an ash
    That shades the road, or setting up a cottage
    Planned in a government office, shorten his life,
    Manacle his soul upon the Red Sea bottom.
    William Butler Yeats (1865–1939)

    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)

    With wonderful art he grinds into paint for his picture all his moods and experiences, so that all his forces may be brought to the encounter. Apparently writing without a particular design or responsibility, setting down his soliloquies from time to time, taking advantage of all his humors, when at length the hour comes to declare himself, he puts down in plain English, without quotation marks, what he, Thomas Carlyle, is ready to defend in the face of the world.
    Henry David Thoreau (1817–1862)
