compute_vi {BCEA} | R Documentation |
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.
compute_vi(Ustar, U)
Ustar |
Maximum utility value (sim x k) |
U |
Net monetary benefit (sim x k x interv) |
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.
