Generating Beta Variates with Nonintegrel Shape Parameters A new rejection method is described for generating beta variates. The method is compared with previously published methods both theoretically and through computer timings. It is suggested that the method has advantages in both speed and programming simplicity over previous methods, especially for "difficult" combinations of parameter values. CACM April, 1978 Cheng, R.
