Research Articles

  1. Practical LDF Interpolation for Well-Behaved IBNR
    Actuaries have devised numerous methods for interpolating annual evaluation loss development factors (LDF) to arrive at quarterly evaluation factors. Not all of these work as well as might be hoped. Some introduce oscillations not found in the …
  2. A Comprehensive, Non-Aggregated, Stochastic Approach to Loss Development
    In this paper, we present a stochastic loss development approach that models all the core components of the claims process separately. The benefits of doing so are discussed, including the provision of more accurate results by increasing the data …
  3. An Alternative Approach to Credibility for Large Account and Excess of Loss Treaty Pricing
    This paper illustrates a comprehensive approach to utilizing and credibility weighting all available information for large account and excess of loss treaty pricing. The typical approach to considering the loss experience above the basic limit is to …
  4. The Mathematics of On-Leveling
    The mathematical foundation of on-leveling premium is explicitly stated. This is combined with an appropriate set of assumptions to derive the formulae for on-leveling premium by rate book (described within) and for using the Parallelogram Method. …
  5. Minimum Bias, GLMs, and Credibility in the Context of Predictive Modeling
    When predictive performance testing, rather than testing model assumptions, is used for validation, the needs for detailed model specification are greatly reduced. Minimum bias models trade some degree of statistical independence in data …
