Univariate cubic L 1 splines provide C 1 -smooth, shape-preserving interpolation of arbitrary data, including data with abrupt changes in spacing and magnitude. The minimization principle for univariate cubic L 1 splines results in a nondifferentiable convex optimization problem. In order to...

Recent literature has advanced the view that the Gibson paradox, or the positive correlation of the price level with nominal interest rates, is nearly always a gold standard phenomenon. We argue that the Gibson correlation is more accurately classified as a statistical artifact of commodity...
