Taking j=1,10000 non-overlapping pairs from generators were formed, and histogram of 100 bins was formed. Their distribution is compared with its theoretical distribution in following figures

Super duper:

There is no large deviance observed, however, the chi-square T with 99 degrees of freedom for the

• unra has value T of 103.12 thus the probability that this value or larger would be seen is 36.63 %
• ran : T=84.53 -> 84.97 % probability
• super-duper:T=72.7 -> 98 % confidence level of agreement between distributions.
