I'm currently looking into some curve-fitting and have examined the
basicGuess(WeightedObservedPoint[])
in GaussianCurveFitter.ParameterGuesser, and there is one thing I don't
really understand.
in Line 301 [1] the "halfY" is computed by n (what is the maximal y
value of the observation) + half the sum of n+m (where m is the x value
of the maximum) applying this to some of my datapoints that fit
relatively good as a Gaussian later, it seems that this condition never
works, and the default in the catch clause is used instead.
I also wonder why x is taken into account for computing the half-y value..
thanks in advance.
