Java programming to sample or sample code for beta distribution, javabeta

This article focuses on the sampling or sampling of beta distribution through Java programming. The details are as follows.

This article uses the Toolkit provided by math3 to sample the beta distribution. The following program samples the beta distribution functions of alpha = 81, beta = 219 and samples 10000 times.

Package function;/*** @ author: School of Management, Hefei University of Technology Qian Yang * @ email: 1563178220@qq.com * @ here the main use of gamma related functions in math3 */import org. apache. commons. math3.distribution. betaDistribution; import org. apache. commons. math3.special. gamma; public class dergamma {public static void main (String [] args) {// sample 1000 times for (int I = 0; I <10000; I ++) {System. out. println (betasampler (81,219) ;}// beta distribution sampling public static double betasampler (double alpha, double beta) {BetaDistribution beta = new BetaDistribution (alpha, beta ); return beta. sample ();}}

Some output results after sampling are as follows:
