Abstract
Performing sensitivity analysis for influence diagrams using the decision circuit frame- work is particularly convenient, since the partial derivatives with respect to every pa- rameter are readily available [Bhattacharjya and Shachter, 2007; 2008]. In this paper we present three non-linear sensitivity anal- ysis methods that utilize this partial deriva- tive information and therefore do not require re-evaluating the decision situation multiple times. Specifically, we show how to efficiently compare strategies in decision situations, per- form sensitivity to risk aversion and compute the value of perfect hedging [Seyller, 2008].
