prototype missing value

Postby Jony » Thu Sep 12, 2013 14:29

Hi,

I am using prototype missing value to remove the attributes which have more that 40% missing value. but why it is removing the rows as well? i have 134 rows and 66 attributes. with this prototype i am removing 26 attributes, but why number of rows get down to 26?

That widget removes all rows where there are any missing values remaining. Unfortunately there is no option for making it remove the attributes only.
