after executing: /opt/local/libexec/perl5.16/sitebin/count.pl test-corpus-count.txt count.txt test-corpus.txt
the output looks fine, as shown/described in 4.1 of http://www.d.umn.edu/~tpederse/Pubs/cicling2003-2.pdf. and then: ~ /opt/local/libexec/perl5.16/sitebin/statistic.pl CHI output.txt test-corpus-count.txt "Error from statistic library! Error code: 101 Error message: Error calculateStatistic() - Mandatory function calculateStatistic() not defined. Your implementation should override this method. Aborting...." So I'm unsure-- in order to use chisq , do I need to implement it? Or the full path? : /opt/local/libexec/perl5.16/sitebin/statistic.pl /opt/local/lib/perl5/site_perl/5.16.1/Text/NSP/Measures/2D/CHI/phi.pm out.txt count.txt Can't locate Text/NSP/Measures/2D// .... Thanks in advance. Best, Patrice
