NAME

spearmans.pl - This program calculates Spearman's Rank Correlation between two datasets.

SYNOPSIS

This utility takes two files in the format of umls-similarity.pl output and calculates the Spearman's Rank Correlation.

USAGE

Usage: spearmans.pl [OPTIONS] FILE1 FILE2

INPUT

FILE1 FILE2

Two files in the following format:

score<>CUI1<>CUI2 score<>CUI3<>CUI4 ect ...

The output format of umls-similarity.pl will work here because it extracts the CUIs from the paranthesis, so no worries. If you are not using the CUI format or a umls-similarity.pl output file though, use the --word option described below.

Optional Arguments:

Displays the quick summary of program options.

--word

The format of the input files contains words rather than CUIs and/or is not a umls-similarity.pl output file.

--N

displays N - the number of term pairs the correlation is being calculated over. This would be any term pair that has a score greater than or equal to zero.

--precision NUMBER

Displays values up to NUMBER places of decimal. Default is 4.

--version

Displays the version information.

OUTPUT

The Spearman's Rank Correlation between the two files.
