GLM Methodology
This tool uses Generalized Linear Models (GLM), the international actuarial standard for non-life insurance pricing. The approach separates frequency (how often claims occur) from severity (how large claims are), then combines them into pure premium relativities.
Frequency Model
Poisson distribution with log link function. Models claim count per policy.
Severity Model
Gamma distribution with log link function. Models average claim amount given a claim occurred.
Pure Premium
Pure Premium = Frequency × Severity. This represents the expected claims cost before expenses and profit loading.
