☞ Quick&Dirty Simulation In Excel

Presented to the monthly Delaware ASA meeting in February 2010.

Abstract:

For all its advantages & disadvantages, Microsoft Excel is an ubiquitous part of statistics today. Since it is limited for complex calculations, statisticians rarely do statistical analyses using Excel. However, it is a standard for data collection and presentation, and provides a common way of communication between statisticians and non-statisticians. Although simulations usually require large numbers of simple calculations, and Excel allows iterative calculations, simulation in Excel usually requires add-in programs, or programming in Visual Basic. However, a few simple programming tricks allow it to be used for simulations without any additional programming, and a few statistical functions programmed in VBA make it useful for a variety of common problems. While Excel simulations can be slow, they inherit many advantages from Excel: ease of coding, debugging tools, graphics, and being understandable by non-statisticians. All VBA code and spreadsheet examples will be posted on the Delaware ASA website.
