The Marsaglia polar method is a pseudo-random number sampling method for generating a pair of independent standard normal random variables. Standard normal random variables are frequently used in computer science, computational statistics, and in particular, in applications of the Monte Carlo method. The … See more 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 x + y … See more A direct application of this idea, $${\displaystyle x={\sqrt {-2\ln(u_{1})}}\cos(2\pi u_{2}),\quad y={\sqrt {-2\ln(u_{1})}}\sin(2\pi u_{2})}$$ is called the Box–Muller transform, in which the chi variate is usually generated as See more This idea dates back to Laplace, whom Gauss credits with finding the above $${\displaystyle I=\int _{-\infty }^{\infty }e^{-x^{2}/2}\,dx}$$ by taking the square root of The transformation … See more Simple implementation in Java using the mean and standard deviation: A non-thread safe implementation in C++ using the mean and … See more WebThe Marsaglia polar method[1] is a pseudo-random number sampling method for generating a pair of independent standard normal random variables.[2] For faster …
