Dear Mr. Weiss and Lachenbruch, I am sorry that I should be more clear when describing my question. In my opinion, I need to be careful about this problem : for example, for a variable that has 10 scales, the 9 value means a real scale and 99 in that case means "not answered". The pattern is like this: (1) if the maximum value of a variable is smaller than 9 , then the "not answered" takes the value 9; (2) if the maximum value of a variable is smaller than 99 but greater than 10, then the "not answered" takes the value 99; (3) if the maximum value of a variable is smaller than 999 but greater than 100, then the "not answered" takes the value 999; and so on. (And you are absolutely right for the reminder that there are values such as 7,8, 98, or 97 to indicate "refused to answer" "invalid answer". Here I would like to keep focus on one example of "not answered" , because the other values could be dealt with using the same way.) Thanks for help from both of you!
