    Re: Resume of "Averaging"
    From: Peter Fogg
    Date: 2004 Nov 5, 18:40 +1100

    If I am the only person who hasn't grasped the nature of the objection below
    then I beg indulgence, but since I am interested in the subject, could
    Herbert try to make more clear just what he means? I have been delving into
    texts on regression but still fail to grasp just what the nature of the
    objection is.
    
    What really perplexes me is that it seems such a simple concept: a given
    slope and data points that can be compared with it. Why does it need to get
    more complicated than that? (leaving aside the non-linearity issue)

    average of the average of two data sets equals, in general, the average
    of the union set of the two data sets?
    
    This is, to wit, in simplified form, the question which is at the basis
    of my most important objection to the method of averaging individual
    "runs" of sights...
