"Association Rules"
I am new at RM and I have been going through the book Data Mining for the Masses. My first question has to do with the operator "Create Association Rules". Under 'Show rules matching' it seems to pick up the first 4 or 5 combination of attributes that come from FP Growth. Can one control which attributes should be shown in the rules?
My second question has to do with how to replace missing values - is there away to replace the missing values with a random allocation of values in a certain percentage. For example, using the Congressional Voting Records from the UCI Machine Learning Repository, is there a way to replace missing votes by a random "yes" or "no" in a proportion of say 60:40?
Thank you
