Abstract

The aim of the work reported here is to contribute to the development of an infrastructure, comprising supporting information and guidelines, to ensure that the use of software, particularly spreadsheets and proprietary software packages, within metrology is made as effective as possible. This is to be achieved by reporting the results of the objective testing of the intrinsic and in-built functions included within spreadsheets and other proprietary software packages that are popular in metrologyapplications.
We describe the application of a general methodology for testing the numerical accuracy of scientific software to specific functions taken from the S-PLUS statistical software package. Each stage of the methodology, from the provision of a specification for each function tested through the definition of performance parameters and measures to the presentation and interpretation of the test results, is presented. In this way, and bystating any assumptions made in the application of the methodology, the testing undertaken is made as objective as possible.
This report constitutes one of the deliverables of Project 2.1 “Testing Spreadsheets and Other Packages Used in Metrology” within the UK Department of Industry’s National Measurement System Software Support for Metrology Programme 1998-2001.
