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!

No limit for generating random numbers as your memory allows.

With NtRand3.2, you can easily generate over **1 MILLION** random numbers on Excel 2007 and 2010.

Soon you will be satisfied with this powerful new tough working add-in.

Long-awaited **NtRand 64bit version** has also finally launched.

Now you can enjoy NtRand3.2 not only on Excel 32bit but also on 64bit.

The following probability distributions applicable to statistical hypothesis test are added:

- Chi square distribution (
**Pearson’s chi square test**,**Yates’chi-square test**,**Mantel-Heanszel chi square test**,**Bartlett test**…) - F distribution (
**F-test**,**Kruskal-Wallis test**,**Friedman test**,**Levene test**…) - Student’s t distribution (
**Student’s t-test, Welch test**…)

Moreover, following probability distributions are also added.

Functions related to above 5 probability distributions and random number generating functions are available on this new Excel-Addin.

Now you can try and enjoy generating random numbers even more!

Sorry! Now a description why it happened is added!

When NtRand became Ver.3 from Ver.2, following functions were deleted.（Check up Release Note）

- NtPCA
- NtOptionBS
- NtOptionBF
- NtOptionGK
- NtMonteCarloLFM

People who have been using NtRand2.0 or former might want to check the differences?

Please see release note.

**You know what, this is the one you should try on!**

Also among all the other generators for Random Numbers, NtRand is outstanding in a way which deals various functions. Besides all these functions, you can also look up all the distributions related.

We recently renewed the software after several requests from all over the world. Come on, don’t waste your time and just get it now!
