This includes methods to trim,\nsubset, merge buckets, merge histograms, convert to CDF, and\ncalculate information loss due to binning. It also provides a\nprotocol buffer representation of R's native histogram class to\nallow histograms over large data sets to be computed and\ncombined in distributed analytical pipelines. Implements\nbin-by-bin histogram distance measures described in Rubner,\nTomasi and Guibas (2000) , Swain\nand Ballard (1991) , and Puzicha,\nHofmann and Buhmann (1997) , and\naverage shifted histograms as in Scott (2015,\nISBN:9781118575536).", "License": "Apache License 2.0", "URL": "https://github.com/murraystokely/histogramtools", "BugReports": "https://github.com/murraystokely/histogramtools/issues", "Classification/ACM": "G.3", "Config/testthat/edition": "3", "Copyright": "Copyright 2011-2015 Google, Inc.
