This is a command line tool that can compute up-down signature probabilities. For more information on up-down signatures see the up-down-signature library.
The tool reads lines of space or comma separated numbers from stdin. The
first line represents the categorical variable which is intepreted as a list
of integers. Subsequent lines are intepreted as lists of doubles. Each line
must have the same number of entries as the first line. The up-down signature
(cumulative) probability is calculated for each line and printed on stdout.
See the sigscore() function in the bapp
library on how to call this tool from within R. Also see the
examples
directory.
Download a binary version and put it somewhere in your path.
Alternatively, clone this repository and build it with cabal:
$ git clone https://github.com/b4winckler/sigscore.git
$ cd sigscore
$ cabal install
Note that this requires that you have installed a Haskell compiler and cabal,
both of which are included in the
Haskell platform.
