BinomialGenerator - how can I set a new value to p?

[axkr]

In BinomialGenerator - how can I set a new value to the private field p?

Should BitString pBits and lastP be defined static as long as p doesn't change?

Which of your Random generators should be preferred in the common case regarding performance and correctness?

Reference: I'm using uncommons-math for the IRandomVariate#randomVariate() method in StatisticsFunctions
