#3129 reviewing defect

VariableRanges of RegressionProblemData are invalid if one NaN is present

Reported by: mkommend Owned by: chaider
Priority: medium Milestone: HeuristicLab 3.3.17
Component: Problems.DataAnalysis Version: trunk
Keywords: Cc:


If any value of a dataset variable is missing (NaN) the whole calculated interval of the variable (variable range) is set to NaN. The reason therefore is the reuse of intervals that have been implemented for a different purpose. Hence, the values of a variable should be filtered for NaNs before the interval / range of a variable is calculated.

r17999: Work on variable range calculation of datasets.

Renamed method to calculate variable ranges to a more appropriate method name. Added possibility to ignore NaNs for range calculation.
