Calculate risk using a Poisson log-normal model. The number of events per time period is calculated using rpois(runs, lambda) and total loss for each time period using sum(rlnorm(events, meanlog, sdlog)).

Usage

calc_risk(risk, lambda, meanlog, sdlog, treatment = "none", runs = 25000)

Arguments

risk

Risk name (a string)

lambda

Parameter passed to rpois()

meanlog

Parameter passed to rlnorm()

sdlog

Parameter passed to rlnorm()

treatment

Risk treatment (a string)

runs

Number of simulations

Value

A tibble of runs rows containing the number of events (events), and the total value of losses (losses) for each run.
