Subject Re: [jira] [Closed] (MATH-649) SimpleRegression needs the ability to suppress the intercept
Date Sat, 10 Sep 2011 15:24:14 GMT
Looks good.  One small thing.  The process we usually follow in
[math] is to RESOLVE when an issue is fixed in trunk and the CLOSE
when a release including the fix has been cut.  So you sort of
jumped the gun on this one.  OK (IMO) to leave this one as is, but
if we want to be tidy, we should reopen and the RESOLVE.

>> 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.
