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 \theta
to reduce the uncertainty in the decisional process.
It is defined as:
\textrm{VI}(\theta) := U^*(\theta) - \mathcal{U}^*
with U^*(\theta)
the maximum utility value for the given simulation
among all comparators and \mathcal{U}^*(\theta)
the expected utility
gained by the adoption of the cost-effective intervention.
