NAME Catmandu::Stat - Catmandu modules for working with statistical data SYNOPSIS # Calculate statistics on the availabity of the ISBN fields in the dataset cat data.json | catmandu JSON to Stat --keys isbn # Calculate statistics on the uniqueness of ISBN numbers in the dataset cat data.json | catmandu JSON to Stat --keys isbn --values 1 # Export the statistics as YAML cat data.json | catmandu JSON to Stat --keys isbn --values 1 --as YAML # Or in fix files # Calculate the mean of foo. E.g. foo => [1,2,3,4] stat_mean(foo) # foo => '2.5' # Calculate the median of foo. E.g. foo => [1,2,3,4] stat_median(foo) # foo => '2.5' # Calculate the standard deviation of foo. E.g. foo => [1,2,3,4] stat_stddev(foo) # foo => '1.12' # Calculate the variance of foo. E.g. foo => [1,2,3,4] stat_variance(foo) # foo => '1.25' MODULES * Catmandu::Fix::stat_mean * Catmandu::Fix::stat_median * Catmandu::Fix::stat_stddev * Catmandu::Fix::stat_variance SEE ALSO Catmandu, Catmandu::Fix, AUTHOR Patrick Hochstenbach, LICENSE AND COPYRIGHT This program is free software; you can redistribute it and/or modify it under the terms of either: the GNU General Public License as published by the Free Software Foundation; or the Artistic License.
