I have 6 attributes: A, B, C, D, Speed, Price.
Speed and price are continuous; conditional pricing is as follows:
Speed = 100, Price = 2, 3, 4
Speed = 400, Price = 4, 6, 8
Speed = 4000, Price = 10, 15, 20
I'm interested in simulations where Speed = 2000 and prices are varied in the range of 10 to 20. However, when I set Speed = 2000, the simulator assumes that Prices 4, 6, 8 are applicable. I'm guessing it views the Speed levels as thresholds for which price sets apply.
When I set Price to a value such as 12, the simulator thinks I'm requesting an "extrapolation." One consequence of this is that it prevents using RFC. I'm able to use Share of Preference with a Price such as 12 but it must be interpolating Speed (since 100 < 2000 < 4000) while extrapolating Price (since 4 < 6 < 8 < 12).
However, in my real-world context, it is more reasonable to assume Prices are in the range of 10 to 20 rather than 4 to 8 when Speed = 2000. Is there a way to configure the simulator to associate the highest price set (10, 15, 20) when Speed = 2000 ?
I've tried hand-calculations on the Excel simulator utilities to replicate the dual interpolation/extrapolation that Share of Preference is performing. I doubt I'll figure out how to extend to RFC. Thus, I was hoping there is a way to change which (conditional) price range the simulator is associating with my interpolated Speed.
