Classical (limited fluctuation):, with Poisson full-credibility standard expected claims set by confidence level and tolerance. Severity and aggregate raise the standard: severity multiplies by, aggregate by, so aggregate always needs the most data. Buhlmann: with; higher process variance lowers, higher between-risk variance raises it. Buhlmann is the best linear unbiased...
