"GaussianFitter" could inherit from "CurveFitter"
-------------------------------------------------
Key: MATH-512
URL: https://issues.apache.org/jira/browse/MATH-512
Project: Commons Math
Issue Type: Improvement
Reporter: Gilles
Priority: Minor
Fix For: 3.0
Currently, the "GaussianFitter" class contains a "CurveFitter" instance (and
delegates most method calls to it) for the sake of being able to return a
"GaussianFunction" instance (from the call to the "fit" method).
I think that it would clearer (in the context of the "fitting" package) that
"fit" returns an array of doubles (as "CurveFitter" does). The user can then
easily create a "Gaussian" function object, if needed.
[Also, note that the "GaussianFitter" actually fits the sum of a constant and a
Gaussian function; thus the name is slightly misleading IMO.]
I also think that "ParametricGaussianFunction" and "GaussianParametersGuesser"
should become inner classes of "GaussianFitter" (as this makes it clear what
their use is).
