Hi Rick,

Thank you for your interesting SAS articles on analytics. I have a question related to weighted mean. I am looking for a method to estimate a weighted mean (score) considering both (i) weights varying based on importance of variables/items used and (ii) importance in considering multiple occurrences (frequency) of an item/variable. Generally weighted average doesn't consider the impacts of multiple occurrences of the same item. How can I make weighted average score based on the impact of both importance and frequency(?) using SAS. Thank you.
