[jira] [Created] (MADLIB-1167) Summary - add more statistics

Frank McQuillan created MADLIB-1167:
---------------------------------------

             Summary: Summary - add more statistics
                 Key: MADLIB-1167
                 URL: https://issues.apache.org/jira/browse/MADLIB-1167
             Project: Apache MADlib
          Issue Type: Improvement
          Components: Module: Descriptive Statistics
            Reporter: Frank McQuillan
             Fix For: v2.0


In the summary function
http://madlib.apache.org/docs/latest/group__grp__summary.html
add additional statistics:

1) % positive values
2) % negative values
3) % zero values
4) confidence intervals (95% ?) on mean
* does this make sense, since need to assume a distribution for the data which we probably cannot infer?
