如何从C中的卡方(1df)分布计算p值? [英] How to calculate the p value from a chi-square (1df) distribution in C?

问题描述

我想知道是否有某种方法可以从C中的给定卡方值(1 df)中计算出p值.我已经尝试了一些ALGLIB函数，但是它没有用(或者我没有用)不知道该怎么做)...

有什么猜想吗?

谢谢

I want to know if there is some way to calculate the p value from a given chi-square value (1 df) in C. I''ve tried some ALGLIB function but it did not work (or I didn''t know how to do it)...

Any guess?

Thank you
