Data sharpening can reduce bias in non-parametric regression and density estimation. Firth’s (1993) approach to bias reduction through adjustment of the score function provides an underlying framework for data sharpening and extensions, such as sha

Conditional expectation imputation and local-likelihood methods are contrasted with a midpoint imputation method for bivariate regression involving interval-censored responses. Although the methods can be extended in principle to higher order polynom

Monte Carlo simulation methods are increasingly being used to evaluate the property of statistical estimators in a variety of settings. The utility of these methods depends upon the existence of an appropriate data-generating process. Observational s

The authors propose a class of procedures for local likelihood estimation from data that are either interval-censored or that have been aggregated into bins. One such procedure relies on an algorithm that generalizes existing self-consistency algorit

Lin and Willmot [Insurance: Mathematics and Economics 27 (2000) 19] derived a set of defective renewal difference equations involving the moments of the time of ruin in the classical insurance risk model. In principal, this allows for evaluation of t

Analytical tools such as Laplace-Stieltjes transforms and z-transforms are commonly used to characterize queueing-theoretic quantities such as busy-period, waiting-time, and queue-size distributions. Many of these transforms, particularly in M/G/1 pr

Intersection matrices help identify the common graphical structure of two or more objects. They arise naturally in a variety of settings. Several examples of their use in a computer algebra environment are given. These include: simplifying an express

Algebraic calculations that depend upon a full partition can be automated through the use of an operator P for the derivation of such a partition. Calculations that require the repeated use of P are automated by simply iterating the operator. The res
