Return value of orngStat.F1 and the like

Postby bgbg » Thu Feb 04, 2010 7:34

In many cases, when the relevant statistics cannot be calculated (for example orngStat.F1, sensitivity etc), the corresponding function returns -1. However, -1 is a perfectly valid output of other statistical parameters such as MCC. Is it possible to change the output value to None?
