Marsaglia polar 法

WebFeb 19, 2014 · I would like to generate an array of normally distributed data around a given mean and withing given upper and lower bounds. I found a function here that uses the Marsaglia polar method (a.k.a polar form of the Box-Müller transformation).. How might I modify this to generate points within -10 and +10 integer values around the mean? WebMarsaglia’s polar method is as follows: Take y1,y2 from uniform distribution on (−1,1) Accept if r2 = y2 1 +y22 < 1, otherwise get new y1,y2 Define x 1 = p −2log(r2)/r2 y1 x2 = p −2log(r2)/r2 y2 Again it can be proved that x1 and x2 are independent N(0,1) random variables. Despite approximately 20% rejections, it is slightly more
