Regression-adjusted estimates for regenerative simulations, with graphics

The independent block structure of regenerative processes and the known convergence rates of the means of ratio estimators are exploited to produce biasreduced regression-adjusted estimates (rare's) for regenerative simulations. Formal and graphical assessments of the evolution of the distributions of the estimates to normafity and symmetry are given. Other graphs show the evolution of the bias in the estimates as well as the bias reduction achieved by the rare estimate.
