Re: Linearisation targets need similar steps?

2012-06-08 by gmikol

I'm surprised Roy hasn't responded to this.

To my understanding, the linearization in QTR assumes equally-spaced points. i.e. if you entered 5 points, it would assume 0,25,50,75,100. 11 points would be 0, 10, 20...100, etc. You could do 4% intervals, wouldn't that be a 26-point linearization?

33 or 34 linearization points would very slightly perturb the linearization curve, you could run some evaluations to determine where that perturbation would have the least effect.
