public class WeightedETGIndicesPostProcessor
extends AWeightedETGPostProcessor<Integer[]>

Computes the ETG index (or indices if we are interpolating) for a given PnL vector and confidence level.

Dependent on the ESConfidenceLevel context value to define the confidence level to use in the calculation.
