Wichmann-Hill Random Number Generator and the Birthday Problem
...andom samples (10M) and any duplicated numbers are not desired. We tried several RNGs in R and found Wichmann-Hill did not produce duplications. The duplication problem is the interesting birthday problem. If there are M possible numbers, randomly draw N numbers from them, the average number of dupilcations D = N(N-1)/2/M. For Knuth-TAOCP and Knuth-TAOCP-2002, M=2^30, since this modulus is used. D = 46566.12 for N=10M samples. For Marsaglia-Multicarry, Super-Duper and Mersene-Twister, M=2^32. D = 11641.53 for N = 10M samples. My testing results (see below) agree with above analysis. But for...

Duplicated packages after yum crash
