Title: SimDesign: An R Package for Executing Monte Carlo Simulation Experiments Author: Phil Chalmers Abstract: Monte Carlo simulation experiments are useful for studying the behaviour of statistical estimates and estimators, particularly in situations where formal statistical theory is intractable or unavailable. At their core, this class of simulation experiments consist of generating random data given a set of simulation design and data-generating characteristics, analyzing said data using one or more inferential methods or competing models, and repeating this generate-analyse sequence numerous times until suitable information can be drawn regarding the behaviour of the population sampling distribution. Results from these analyses are then summarized using suitable meta-statistical methods and subsequent graphical presentations, often for the purpose of dissemination. This talk will provide an overview of how the R package "SimDesign" can be used for designing and streamlining such simulation experiments. The general structural philosophy of the package will be discussed, along with the associated implementation, organization, debugging, and safety features that are desirable when constructing (and reconstructing) the associated computer code for intensive simulation experiments.
