Computes the cumulative binomial function.

Member Function Documentation

compute()

static double compute ( Size  n, Size  k, double  p  )

static

Compute the cumulative binomial function.

Sums up ( n choose i ) * p^i * (1-p)^(n-i) for i from 0 to k.

Note

if the binomial coefficient ( n choose k ) overflows, it is set to the numeric limit for the double type

Parameters

n,size	of theoretical spectrum
k,number	of matched peaks
p,probability	of a random match between a theoretical and an experimental peak
