Whether the scale (ordinate) is linear of log, the fit is the same.

Really? I must be misunderstanding that sentence, because I

effect on the weights. Indeed this is an arcane but effective
way of controlling the weights, if that's what you want, as
discussed below.

Here’s an example of what I meant:

bc thinks he didn’t “scale" the data, just placed them on the graph differently. Evidently is in a "teachable moment”.
