I am trying to incorporate an integration routine to calculate the area under an F-Distribution given a score and the numerator and denominator DOFs. I've made similar routines for the normal and T distributions. The F-distribution is giving me some problems, especially when my DOFs are small. I get good results using DOF of 5 or greater, but if I use 2 or 1, I'm way off. Is there some trick or alternate way to integrate this distribution? I am just summing slices under the curve now.
