## Improved estimates for the CPO/PIT-values

### Description

Improve the estimates of the CPO/PIT-values be recomputing the model-fit by removing data-points.

### Usage

    inla.cpo(
      result,
      force = FALSE,
      mc.cores = NULL,
      verbose = TRUE,
      recompute.mode = TRUE
    )

### Arguments

`result` | An object of class `inla`, ie a result of a call to `inla()`
`force` | If TRUE, then recompute all CPO/PIT values and not just those with `result$cpo$failure > 0`.
`mc.cores` | The number of cores to use in `parallel::mclapply`. If `is.null(mc.cores)`, then check `getOption("mc.cores")` and `inla.getOption("num.threads")` in that order.
`verbose` | Run in verbose mode?
`recompute.mode` | Should be mode (and the integration points) be recomputed when a data-point is removed or not?

### Value

The object returned is the same as `result` but the new improved estimates of the CPO/PIT values replaced.

### Examples

    n = 10
    y = rnorm(n)
    r = inla(
      y ~ 1,
      data = data.frame(y),
      control.compute = list(cpo=TRUE),
      num.threads = "1:1" # Protect package testing from parallel execution
    )

    rr = inla.cpo(r, force=TRUE)
