> Project: Mahout
> Issue Type: Bug
> Components: Algorithms
> Affects Versions: 0.13.0
> Reporter: Trevor Grant
> Assignee: Trevor Grant
> Fix For: 0.13.0
>
>
> Anecdotally, the p-values reported by the ordinary least squares model
> (utilizing the functionality in the parent, LinearRegressionFitter) have been
> reported outside the range of [0,1] which is nonsensical.
> Need to recreate problem with toy data set, fix, and add test.
