We are pleased to announce the release of version 1.25 of the Ngram statistics package. This is available from CPAN or sourceforge, and you can find download links here :
http://ngram.sourceforge.net There are two important changes in this release : First, the rank.pl program (which computers spearman's correlation) has been modified to properly handle ties in ranks. Previous versions may result in correlation scores that are artificially high, so please get the new version if you rely on that or plan to use it. Second, the t-score has been extended to 3-grams and 4-grams. Below is the change log for the release. Please let us know of any questions or concerns. Cordially, Ted ============= 1.25 Release Jan 15, 2012 all changes by BTM * Added tscore for 3D and 4D along with test cases * Updated rank.pl to work with ties * Added --N option to rank.pl to return the number of ngrams being used to calculate the correlation.
