Abstract: This report describes an interactive computer program that facilitates efficient measurement of communication system performance parameters. The program performs three primary functions: (1) determines the minimum sample size required to achieve a desired precision in estimating delay, rate, or failure probability parameters; (2) analyzes measurement results to determine the precision achieved; and (3) tests independent sets of measured data for statistical homogeneity. The report discusses statistical concepts underlying the program, shows how each function is performed, and provides comprehensive program documentation in the form of mathematical formulas, structured design diagrams, and the program listing. The program was written specifically to facilitate measurement of the performance parameters defined in a newly approved Data Communication Standard, American National Standard X3.l02. The statistical techniques implemented in it may also be applied to any other delay, rate, or failure probability measurement. The program is written in ANSI (1977) standard FORTRAN to enhance its portability. It is available from the author at duplication cost.
