ConfInt.pm, Version 1.0.1 NAME ConfInt ConfInt - Perl extension for calculating the confidence interval of meassured values. SYNOPSIS use ConfInt; ConfInt([ARGUMENT_1],[ARGUMENT_2]); DESCRIPTION This module calculates and returns the relative error of the turned over values. ConfInt needs two things to be turned over: 1st is the width of the confidence interval. 2nd is the reference to an array including the values. Supported confidence interval width: 0.7 (+/- 0.35) ; probability of 0.65 0.6 (+/- 0.30) ; probability of 0.70 0.5 (+/- 0.25) ; probability of 0.75 0.4 (+/- 0.20) ; probability of 0.80 0.3 (+/- 0.15) ; probability of 0.85 0.2 (+/- 0.10) ; probability of 0.90 0.1 (+/- 0.05) ; probability of 0.95 0.05 (+/- 0.025); probability of 0.975 0.02 (+/- 0.01) ; probability of 0.99 0.01 (+/- 0.005); probability of 0.995 EXAMPLE: use ConfInt; @ValueArray = (1,1,1,1,1,2,3,2,1,1,1,1,2,1); $ReturnValue = &ConfInt::ConfInt(0.05,\@ValueArray); print "$ReturnValue"; EXPORT Returns the relative error of a summary of values.
