NtRand

Standing on the shoulders of Giants : NtRand3.3 rises. Achieving the precision of Excel 2010.

By adopting the calculation algorithm of Boost, the pioneering C++ open source library, NtRand 3.3 has greatly improved the accuracy of its distribution functions. In addition to this enhancement, NtRand 3.3 introduces seven new functions.

The precision of each distribution function in NtRand 3.3 now closely matches its corresponding Excel 2007 and 2010 function*.

For probability density function and cumulative distribution function of normal distribution—the most important distribution for every field—NtRand 3.3 can produce accurate values within the vast range of , which was only previously.

Improved distribution functions:

NTBETADIST
NTCHIDIST
NTCHISQDIST
NTGAMMADIST
NTJOHNSONSUDIST
NTJOHNSONINV
NTLOGNORMDIST
NTLOGNORMINV
NTNORMDIST
NTNORMINV
NTTDIST
NTTRUNCNORMDIST
NTTRUNCNORMINV
NTWEIBULLDIST
NTWEIBULLINV

New functions:

NTBETAINV
NTCHIDISTINV
NTCHISQINV
NTFDISTINV
NTGAMMAINV
NTPOISSONDISTINV
NTTDISTINV

Last but not least, the most remarkable improvement is …….the removal of the irritating dialog box during start up!
