> URL: https://issues.apache.org/jira/browse/MATH-1167
> Project: Commons Math
> Issue Type: Bug
> Affects Versions: 3.3
> Environment: jdk1.7_71, OSX 10.10

> A fix was made for this issue in MATH-1110 for the newSampleData method but
> not for the newXSampleData method.
> It's a simple change to propagate the threshold to QRDecomposition:
> 237c237
> < qr = new QRDecomposition(getX());
> ---
> > qr = new QRDecomposition(getX(), threshold);
