---------------------------------------
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?
