I currently try to find an open source C/C++statistical library. Basically, I want to calculate the p and F value from oneway (or N way anova). Does anyone know where downloadable ( free) c/c++ statiscal library ?
I've done a little bit of programming in C, but mostly in VB - if you can't find an ANOVA library, it shouldn't be that big of a deal to create your own 1-way ANOVA function....right? I've done similar types of things, and once you do it, it comes in very handy....
thank a lot guys,
I did write a program to do one way anova . The big deal in here is that I could not find how to calculate the p value from the f value. :shakehead
You guys have any ideas about how to calculate p value from f value in anova function? such as some formulars ???
I found in Mathlab the functions call
Pvalue = 1 - fcdf (Fvalue, degree_freedom(1), degree_freedom(2));
however, it is too hard to write a function fcdf because inside this function has a nested other functions that is impossible to implement in C++.
