  A review study of NIST Statistical Test Suite is undertaken with a motivation
to understand all its test algorithms and to write their C codes independently
without looking at various sites mentioned in the NIST document. All the codes
are tested with the test data given in the NIST document and excellent
agreements have been found. The codes have been put together in a package
executable in MS Windows platform. Based on the package, exhaustive test runs
are executed on three PRNGs, e.g. LCG by Park & Miller, LCG by Knuth and BBSG.
Our findings support the present belief that BBSG is a better PRNG than the
other two.
