Description: Discusses the Canadian Institute of Actuaries' disability morbidity study to update the 1964 CDT and explains the techniques used to interpolate incidence rates from the 1964 CDT.

Description: This paper presents an unbiased, consistent and asymptotically efficient estimator based on importance sampling variance reduction technique in the framework of Monte Carlo simulation methods. It shows that the estimator is highly efficient in terms of number of computations. Using the Pollaczeck-Khinchine formula, the authors extend the use of the estimator to the calculation of ultimate ruin probabilities in the context of the Classical case of Risk Theory and compare their results with recent actuarial literature using the same methodology.

Description: The Cauchy integral formula is applied to derive various results on divided differences.

Description: This paper attempts to broaden the actuary's understanding of decrement rate estimation and to clear up some of the more common misconceptions which have been promoted.

Description: This paper discusses a class of asymmetric distributions arising in a random summation scheme. Members of the class are called asymmetric Laplace distributions as the standard Laplace distributions, which are symmetric, constitute a proper subclass. Among distributions which are limits in random summation schemes, asymmetric Laplace distributions play an analogous role to that of normal distributions among distributional limits of non-random sums. Asymmetric LaPlace laws are more 'peaky' and have heavier tails than normal laws. They have stability properties and are convenient in applications, as their densities have explicit forms and estimation procedures are easily implemented. Anticipating increasing interest in this class of distributions, the authors present statistical tools which can be utilized in practice, including algorithms for simulation and estimation. They also discuss more general classes of distributions, where asymmetric Laplace distributions appear as special cases.

Description: Presents a theoretical basis for a computerized methodology for estimating biological age - a measure of time to death.
