Enhanced analytics help predict claim severity and frequency earlier, improving the accuracy of IBNR estimates [1-5]. Conclusion

: A general reserve pool set aside for groups of claims where case reserves are expected to be inadequate.

This method calculates a rate from scratch using exposure units (e.g., one car insured for one year is one car-year exposure). : Gross Rate Formula : 2. The Loss Ratio Method

: Severe events like hurricanes or earthquakes do not happen every year. Actuaries use computer models to simulate thousands of years of weather data to smooth out these spikes.

This calculates the "pure premium"—the expected cost of losses per unit of exposure—and then loads it with expenses and profit.
