Phil Steitz commented on MATH-664:
----------------------------------
I think that to meet the practical need that led you to open this, that is
going to be needed, so I would say first just patch the current LU-based impl
to allow the threshold parameter.
> Replace "LUDecompostionImpl" with "QRDecompositionImpl" in
> "AbstractLeastSquaresOptimizer"

> In some cases, the "getCovariances()" method throws a
> "SingularMatrixException". This can be avoided by using "QR" instead of "LU"
> decomposition.
