nlirms package design the non-life insurance rate-making system based on the posteriori frequency and severity component. The non-life insurance rate-making system is a actuarial system for pricing of non-life insurance contract. This system determinates fair rates and fair premiums for each of policyholders based on the claims frequency and severity history of policyholders in last years.
usually a rate-making system is designed from three way:
1-rate-making system based on the freuency component
2-rate-making system based on the severity component
3-rate-making system based on the both freuency and severity component
nlirms package returns rate-Making system based on each of the three methods. in current version of nlirms package, five model can be applied for frequency component and also five model can be applied for severity component.
