Student Distribution

 [1/6] from: lmecir:mbox:vol:cz at: 20-Feb-2002 13:05


I would like to define a Rebol function, that can compute values of the Student Distribution. Any pointers? TIA Ladislav

_Numerical_Recipes__The_Art_of_Scientific_Computation_ by Press, Flannery, Teukolsky, and Vetterling (c) Cambridge University Press, 1986 ISBN 0-521-30811-9 describes the mathematics of Student's t and the incomplete beta function in chapters 6 and 13, and presents both FORTRAN and PASCAL code for the relevant functions. There is a later edition of that book that uses C as the demo language, if that's of any help. -jn- -- ; sub REBOL {}; sub head ($) {@_[0]} REBOL [] # despam: func [e] [replace replace/all e ":" "."

That's probably not to difficult: print "In the pub" would be a good enough approximation of student distribution ;) Chris -- .------{ http://www.starforge.co.uk }-----. .--------------------------. =[ Explorer2260, Designer and Coder \=\ P: TexMaker, ROACH, site \ =[___You_will_obey_your_corporate_masters___]==[ Stack: EETmTmTRRSS------ ]

Thanks, how about the Cumulative Student Distribution function, do I have to use numerical integration? ----- Original Message ----- From: "Joel Neely" <[joel--neely--fedex--com]> To: <[rebol-list--rebol--com]> Sent: Wednesday, February 20, 2002 2:22 PM Subject: [REBOL] Re: Student Distribution Hi, Ladislav, Ladislav Mecir wrote:

The book's at my house. I'll try to check on that this evening. -jn- Ladislav Mecir wrote:
