Description

If just one value of a feature is missing, no correlation will be calculated and double.NaN is displayed. Hence, an option to ignore missing values should be added to the correlation calculation.

Reviewed r13938.

The changes are ok. The only question I have is why was the splitContainer introduced?

Replying to gkronber:

The SplitContainer was already present in the base class for aligning additional controls nicely. By adding the checkbox and resizing the view it shows up in the derived view as well.
