Simulate individual claim severities

Samples independent nonnegative claim amounts from an actuarial severity specification, including atoms at zero when present. A realization is one individual claim amount, not an aggregate or a fitted severity estimate.

Usage

simulate_severity(x, n_sim = 1000L, seed = NULL)

Arguments

x

A [severity_spec()], [empirical_severity()], or compatible payment severity specification.

n_sim

Positive integer number of simulations.

seed

Optional nonnegative integer seed; preserves the caller's RNG state when supplied.

Value

A tibble with `simulation` and `claim_amount` columns.

Details

A missing RNG provider produces an explicit error. Zero severities are retained; no implicit conversion from per-loss to per-payment basis takes place.

Examples

simulate_severity(severity_spec("exponential", rate = 0.002),
                  n_sim = 5, seed = 20)
#> # A tibble: 5 × 2
#>   simulation claim_amount
#>        <int>        <dbl>
#> 1          1         96.7
#> 2          2         29.2
#> 3          3         31.7
#> 4          4       1106. 
#> 5          5        502.
