How to impute the missing data with the most frequent value
Contributor I
I have a dataset containing categorical and numerical data and I would like to know how I can impute the missing data with the frequent value.
For example
ID Feature1 Feature 2 Feature 3
_______________________________________
123 core i7 Windows 33844690
334 IOS phone 99983648
Note that the missing values are huge but I can't drop the column.
Is there an operator I can use for nominal data to be replaced with the mode? and the numerical data with average or max?

Hi,you can use Replace Missing Values. Average actually takes the mode for nominal columns.Cheers,Martin- Sr. Director Data Solutions, Altair RapidMiner -
