Filtering ALL Examples (no. of missing data in the attribute = total no. of examples)
I would like to filter out all missing data. Where the number of missing data in the attribute is equal to the total number of examples.
I know Select Attribute can do the trick. However, as I have roughly 20-30 attributes where all examples missing, so I would not like to pick it out individually.
I've tried using Filter Examples > no_missing_attributes, but I have no idea why I ended up with no examples at all from 2041 examples.
Thank you!

AY
