Detailed Description

Implements a fitter for the Gumbel distribution.

This class fits a Gumbel distribution to a number of data points. The results as well as the initial guess are specified using the struct GumbelDistributionFitResult.

The formula with the fitted parameters can be transformed into a gnuplot formula using getGnuplotFormula() after fitting.
