i would like to ask you how to deal correctly with missing value in KNIME.
Sometimes I have (correctly) missing values (it is not a mistake) and in KNIME Console I receive some warning message:
due to this there is Missing Value Node. For numbers I can fill with “0”, but how to deal with string contains "? " Leave “?” or use Missing Value Node and choose Do nothing or what is the correct approach?
Thank you in advance
