And I already demonstrated that deep and practically very relevant difference with a suitable example. Heikki's only criticism of that example boils down to a question whether an example with duplicate rows has legitimacy in the first place.

I have verified it many times while cleaning up the messes caused by naive data modellers who actually fell for this sort of sophistry. In fact, I devised the example on the basis of my own empirical recollections.

As you say, I have provided an empirically falsifiable hypothesis. Again, the burden lies on Heikki to actually measure his speculation that empiricism would in fact falsify it. He is welcome to do so at any time.

The sophistry we are discussing does not relate to Lauri's anecdote. What is your purpose in focussing on Lauri's example for which I gave no defense while offering no acknowledgement of the empirical justification I gave for my own hypothesis? Received on Sun Aug 31 2003 - 18:09:34 CEST
