Running OriginPro 8.1 on win 7
Hi
Im looking for a factorial function in origin for use in a fitting function to a binomial distribution. Earlier posts (2000 - 2005) claim its not in origin and give access to a script that i assume would work pooly in a compiler. Is there a factorial function somewhere, or how can i work around this ?
Thanks, Nils |

You needn't use factorial function. OriginC provides binocdf function to calculate binomial distribution for X<=k, X>k or X=k.
For more information, see the page.

Hi Nils,
You are right, you can use gamma() function now. In the coming version, Origin 8.6, the factorial function, fact(), will be available.

...of course, the gamma function can do this, gamma(x+1) - doh! |
