                 Key: MATH-649
                 URL: https://issues.apache.org/jira/browse/MATH-649
             Project: Commons Math
          Issue Type: New Feature
    Affects Versions: 3.1
         Environment: JAVA
            Reporter: greg sterijevski
            Priority: Minor
         Attachments: simplereg, simpleregtest

The SimpleRegression class is a useful class for running regressions involving 
one independent variable. It lacks the ability to constrain the constant to be 
zero. I am attaching a patch which gives a constructor for setting NOINT. I am 
also checking in two NIST data sets for noint estimation.
