Calibration Report Interpretation

Post by andrerpsimoes »

Hello, could you explain to me what the meaning of the " * " (asterisk) before variables on the results below?
Thanks.

Initial point of search
Seasonality Amplitude = 0.1
"Sensitivity of Milk Per Cow to Milk/Feed Cost" = 0.15
Potential Milk per Cow Growth Rate = 0.02
Production Practice Adjustment Time = 2
Reference NFOI = 650
"Long-term Market Observation Adjustment Time" = 6
Sensitivity of Culling to AD ratio = 0.75
Sensitivity of Cull Cow Price to Relative Culling Rate = -1
Cull Cow Price Adjustment Time = 3
Reference Inventory Coverage[Fluid] = 2

As I recall, it just signals a change on the last pass. Nothing terribly interesting.

When you're doing payoff sensitivity experiments, a * signals that a bound has been reached, which is more interesting.
