Computes -log10(NFA). NFA stands for Number of False Alarms: @f[ \mathrm{NFA} = NT \cdot B(n,k,p) @f] - NT - number of tests - B(n,k,p) - tail of binomial distribution with parameters n,k and p: @f[ B(n,k,p) = \sum_{j=k}^n \left(\begin{array}{c}n\\j\end{array}\right) p^{j} (1-p)^{n-j} @f] The value -log10(NFA) is equivalent but more intuitive than NFA: - -1 corresponds to 10 mean false alarms - 0 corresponds to 1 mean false alarm - 1 corresponds to 0.1 mean false alarms - 2 corresponds to 0.01 mean false alarms - ... Used this way, the bigger the value, better the detection, and a logarithmic scale is used. @param n,k,p binomial parameters. @param logNT logarithm of Number of Tests The computation is based in the gamma function by the following relation: @f[ \left(\begin{array}{c}n\\k\end{array}\right) = \frac{ \Gamma(n+1) }{ \Gamma(k+1) \cdot \Gamma(n-k+1) }. @f] We use efficient algorithms to compute the logarithm of the gamma function. To make the computation faster, not all the sum is computed, part of the terms are neglected based on a bound to the error obtained (an error of 10% in the result is accepted).
