:: DeveloperApi :: A class with pseudorandom behavior.
:: DeveloperApi :: A pseudorandom sampler.
Object used by seqOp to keep track of the number of items accepted and items waitlisted per stratum, as well as the bounds for accepting and waitlisting items.
:: DeveloperApi :: A sampler based on Bernoulli trials for partitioning a data sequence.
:: DeveloperApi :: A sampler based on Bernoulli trials.
Utility functions that help us determine bounds on adjusted sampling rate to guarantee exact sample size with high confidence when sampling without replacement.
advance to first sample as part of object construction.
