Negative chi^2 from Commander
Posted: October 22 2013
Dear all,
when I run with feedback=3, the following LnLike and Chi2 are printed for the individual datasets:
Why is there a negative chi2 from commander? And secondly, isn't the BAO chi2 very low?. I first discovered this in a modified Jun2013 version, but I could reproduce it with a vanilla Oct2013 one.
Cheers,
Björn
