UnverifiedTraditional DRO methods exhibit a non-vanishing robustness floor under model misspecification, meaning a lower bound on decision risk that cannot be reduced regardless of how much data is available.80% similarUnverifiedDT-DRO distorts the underlying cost using bias information obtained from PIT diagnostics, deforming the spherical ambiguity set into an ellipsoid aligned with the principal axes of the error distribution.80% similarUnverifiedTotal prediction error can be decomposed into bias² + variance + irreducible error.73% similarUnverifiedThe core idea of distributionally robust optimization (DRO) is to optimize worst-case performance within an ambiguity set, without assuming the data distribution is fully known.72% similarUnverifiedWhen measuring prediction error after fractional integration, there is an exact 1/L leading-order error for forecasting from a finite context of length L.71% similar
