#881 closed defect (worksforme)

StablePearsonCorrelationCoefficientCalculator sometimes returns NaN values.

Reported by: gkronber Owned by: gkronber
Priority: medium Milestone: HeuristicLab 3.3.0
Component: Problems.DataAnalysis Version: 3.3.0
Keywords: Cc:

Description

All modeling result collectors should behave identically when the result is undefined. Other correlation calculators return a default value (e.g. 0.0) when there is an exception in the calculation of results.

Added a check to SimpleStableCorrelationCoefficientEvaluator so that a r2 of 0.0 is returned instead of NaN (in case of division by zero). Also removed unnecessary try {} catch block in SimplePearsonCorrelationCoefficientEvaluator with r2844.
