Hi Muthen's, I was at the training in Baltimore last week. It was really a lot of fun and incredibly helpful in terms of generating new ideas. Linda, there's something you mentioned very briefly near the end of the last day and I wanted to follow up with you. You stated that when combining items from a scale to create a mean score, those items have to all function on the same dimension. Items measuing multiple dimensions of a construct cant be totalled in this way. I understand this conceptually, but could you point me to an article or two that makes this point explicitly. It fits in very well for a paper I'm working on right now.
Thanks again for last week. It really was great. Best, Isaac
