Class GaussianCurveFitter

java.lang.Object
org.hipparchus.fitting.AbstractCurveFitter

public class GaussianCurveFitter extends AbstractCurveFitter
Fits points to a Gaussian function.
The initial guess values must be passed in the following order:
  • Normalization
  • Mean
  • Sigma
The optimal values will be returned in the same order.

Usage example: 

   WeightedObservedPoints obs = new WeightedObservedPoints();
   obs.add(4.0254623,  531026.0);
   obs.add(4.03128248, 984167.0);
   obs.add(4.03839603, 1887233.0);
   obs.add(4.04421621, 2687152.0);
   obs.add(4.05132976, 3461228.0);
   obs.add(4.05326982, 3580526.0);
   obs.add(4.05779662, 3439750.0);
   obs.add(4.0636168,  2877648.0);
   obs.add(4.06943698, 2175960.0);
   obs.add(4.07525716, 1447024.0);
   obs.add(4.08237071, 717104.0);
   obs.add(4.08366408, 620014.0);
   double[] parameters = GaussianCurveFitter.create().fit(obs.toList());
