accurate algorithms possible. The programs have
been tested and verified over and over, both by
us and by our customers. Each routine has been
verified against textbooks, journal articles,
and, where possible, other software. NCSS is one
of the most accurate statistical analysis
programs available. NCSS calculates with
seventeen-digit, double-precision accuracy. |
