I’m working on a dataset regarding cancer. In particular i have a column named “Pregnancies” and a column named “Age”. I have several missing values for “Pregnancies” and i would like to replace them with the most frequent value for her “Age”. Can someone please explain me how to do that?
Thank you in advance.
@stefano250396 welcome to the KNIME community.
- Group by Age and Mode of no Pregnancies
- Left Join this data back by Age as ID
- Use a Rule Engine to replace missing values with this mode value
MISSING $Pregnancies$ => $Pregnancies (Mode)$
TRUE => $Pregnancies$
Thank you very much =D
