fitevd <query length> [options]
fitevd fits an extreme value distribution to a set of score-length pairs.
The outer loop alternates between estimating lambda and K with H fixed and estimating H with lambda and K fixed. The inner loop is the Newton-Raphson algorithm, which is used for solving the estimation problems.
Reads white-space separated score-length pairs from standard input.
The query length.
Writes the EVD parameters to standard output.
