CHICOM: A code of tests for comparing unweighted and weighted histograms and two weighted histograms
چکیده انگلیسی

A Fortran-77 program for calculating test statistics to compare weighted histogram with an unweighted histogram and two histograms with weighted entries is presented. The code calculates test statistics for cases of histograms with normalized weights of events and unnormalized weights of events.Program summaryProgram title: CHICOMCatalogue identifier: AEKE_v1_0Program summary URL:http://cpc.cs.qub.ac.uk/summaries/AEKE_v1_0.htmlProgram obtainable from: CPC Program Library, Queenʼs University, Belfast, N.

► Program code of tests for comparing two weighted histograms and unweighted histogram with weighted histogram is presented.
► Tests are generalization of classical chi-square test that is used for comparing histograms with unweighted entries.
► Program calculates test statistics for comparing histograms with normalized weights as well as with unnormalized.
