spouvrea	Posted - 09/25/2007 : 7:16:58 PM Hi. I would like to add a new fitting equation, to fit a histogram using the Poisson distribution. How can I do that? Thanks

Mike Buess	Posted - 09/25/2007 : 9:20:26 PM In all Origin versions you can use LabTalk's poisson function... quote: Poisson(npts, mean, seed) The poisson(npts, mean, seed) function returns npts number of random integers having a Poisson distribution with mean mean. Seed is optional. In Origin 7.0 or 7.5 you can also use nag_poisson_dist, see Help> Programming> Origin C Language Reference> Global Functions> NAG Functions> Simple Calculations on Statistical Data For general instructions on defining new fitting functions see http://www.originlab.com/www/helponline/origin/Defining_a_New_Function_.htm - and - Help> Origin> Tutorials> Origin Tutorials> Tutorial 11... Defining a New Fitting Function As for fitting a histogram see this topic... http://www.originlab.com/forum/topic.asp?TOPIC_ID=6082 Mike Buess Origin WebRing Member Edited by - Mike Buess on 09/25/2007 9:51:14 PM Edited by - Mike Buess on 09/25/2007 9:59:55 PM
