I am usually pretty good at reading what has been presented, but this one is eluding me so far. (I see the foreign address; however, the poster's English seems excellent.) Objects. Objects that are grouped. Let me see -- here is a "bag of vegetables" , and over there are "automobile parts". For items in both, I can describe weight, height, color, cost - for each total, or for the items. But "dependent variables" -- I only have the cost of the *bag* of vegetables? The abstraction so far has defeated my attempts to find a concrete problem. > Thus, I could identify the correlation using the mean values per group > of the independet variables. > > Is there any possibility to include more information of the objects > (e.g. distribution, quartiles) into the correlation?
