Hi
I am wanting to know why the RapidMiner Declare missing values operator does not seem work correctly in flagging specific values (such as in the data set I am working which lists missing values as NA) as missing values for variables that are type polynominal.  It seem consider all possible values for a polynominal variable being ok because these are text categories etc
Any help or advice on the above would be much appreciated
Best regards Michael
