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
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.
