Marsaglia Polar Method - Theoretical Basis

Theoretical Basis

The underlying theory may be summarized as follows:

If u is uniformly distributed in the interval 0 ≤ u < 1, then the point (cos(2πu), sin(2πu)) is uniformly distributed on the unit circumference x2 + y2 = 1, and multiplying that point by an independent random variable ρ whose distribution is

will produce a point

whose coordinates are jointly distributed as two independent standard normal random variables.

Famous quotes containing the words theoretical and/or basis:

    There are theoretical reformers at all times, and all the world over, living on anticipation.
    Henry David Thoreau (1817–1862)

    This seems to be advanced as the surest basis for our belief in the existence of gods, that there is no race so uncivilized, no one in the world so barbarous that his mind has no inkling of a belief in gods.
    Marcus Tullius Cicero (106–43 B.C.)
