             Summary: OLSMultipleLinearRegression STILL needs a way to specify non-zero singularity threshold when instantiating QRDecomposition
                 Key: MATH-1167
                 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
            Reporter: Neil Ireson
            Priority: Critical


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);
