CHIWEI: A code of goodness of fit tests for weighted and unweighted histograms

A Fortran-77 program for goodness of fit tests for histograms with weighted entries as well as with unweighted entries is presented. The code calculates test statistics for case of histogram with normalized weights of events and in case of unnormalized weights of events.Program summaryProgram title: CHIWEICatalogue identifier: AEKQ_v1_0Program summary URL:http://cpc.cs.qub.ac.uk/summaries/AEKQ_v1_0.htmlProgram obtainable from: CPC Program Library, Queenʼs University, Belfast, N.
