## Uses of Class
cern.jet.random.engine.RandomEngine

Packages that use RandomEngine
cern.colt.matrix.doublealgo | Double matrix algorithms such as print formatting, sorting, partitioning and statistics.
cern.jet.random | Large variety of probability distributions featuring high performance generation of random numbers, CDF's and PDF's.
cern.jet.random.engine | Engines generating strong uniformly distributed pseudo-random numbers; Needed by all JET probability distributions since they rely on uniform random numbers to generate random numbers from their own distribution.
cern.jet.random.sampling | Samples (picks) random subsets of data sequences.
cern.jet.stat.quantile | Scalable algorithms and data structures to compute approximate quantiles over very large data sequences.
hep.aida.bin | Multisets (bags) with efficient statistics operations defined upon; This package requires the Colt distribution.
