------------------------------------
Summary: Condition No. is the same value for all groups in output
of linear regression with grouping cols
Key: MADLIB-1211
URL: https://issues.apache.org/jira/browse/MADLIB-1211
Project: Apache MADlib
Issue Type: Bug
Components: Module: Linear Regression
Reporter: Rashmi Raghu
The model output table for linear regression contains a column for condition
number of the matrix. The value in this column is the same for all groups when
linear regression is run with grouping columns (an unlikely occurrence in any
realistic dataset).
