## 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 `\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.

### Value

Array with dimensions (sim x k)
