Compute Value of Information

Description

The difference between the maximum utility computed for the current parameter configuration U^* and the utility of the intervention which is associated with the maximum utility overall.

Usage

compute_vi(Ustar, U)


Arguments

 Ustar Maximum utility value (sim x k) U Net monetary benefit (sim x k x interv)

Details

The value of obtaining additional information on the parameter θ to reduce the uncertainty in the decisional process. It is defined as:

\textrm{VI}(θ) := U^*(θ) - \mathcal{U}^*

with U^*(θ) the maximum utility value for the given simulation among all comparators and \mathcal{U}^*(θ) the expected utility gained by the adoption of the cost-effective intervention.

Value

Array with dimensions (sim x k)
