An approach with which actuaries do appear comfortable is based on scaling. Panning (2006) argues that loss reserve uncertainty under his method is “scalable.” By that he means that his method’s coefficient of variation (CV) “is applicable to reserves that have been estimated in different ways” (Panning 2006). Scaling is an actuarial technique utilized in a wide variety of applications. In stochastic analysis the authors are aware that it is common practice to apply a CV based on the Mack method to a chain-ladder point estimate that is based on selected factors other than the all-year volume-weighted average. The authors are concerned that bifurcated point and variability estimates may underestimate the volatility of the underlying claims process.
