Available statistics are either
If output option is specified, results are written to file or
stdout in stead of attribute table of the input map.
File output is produced with the following column order:
cat | prefix | buffer| statistic/measure | value
separated by the user defined separator (default is |).

The module is affected by the following underlying library issues: Lines are wrongly reported for points maps: https://trac.osgeo.org/grass/ticket/3549 To circumvent the issue, specify the type of geometry to process in the module call using the type option. Currently, the module uses GRASS native buffering which should be replaced by buffering using GEOS: https://trac.osgeo.org/grass/ticket/3628
