Robust monetary rules under unstructured and structured model uncertainty [PDF]

This paper compares two contrasting approaches to robust monetary policy design. The first developed by Hansen and Sargent (2003, 2007) assumes unstructured model uncertainty and uses a minimax robustness criterion to design monetary rules.

Model-Robust Interval Estimation

, 2003
Confidence intervals are one of the most useful statistical tools. This dissertation is a study of several methods for forming confidence intervals that are insensitive to model assumptions, provided that the mean model for the data is not misspecified.

Deep learning and superoscillatory speckles empowered multimode fiber probe for in situ nano-displacement detection and micro-imaging

Nature Communications
High-precision metrology has laid the foundation for semiconductor fabrication and life sciences. However, existing displacement measurement approaches are incapable of performing flexible probing within complex equipment interiors. Here, we present a in

Robust Utility Maximization in a Stochastic Factor Model [PDF]

We give an explicit PDE characterization for the solution of a robust utility maximization problem in an incomplete market model, whose volatility, interest rate process, and long-term trend are driven by an external stochastic factor process. The robust

Robust estimation of the vector autoregressive model by a trimmed least squares procedure. [PDF]

The vector autoregressive model is very popular for modeling multiple time series. Estimation of its parameters is done by a least squares procedure. However, this estimation method is unreliable when outliers are present in the data, and there is a need

Robust estimation of nonlinear model coefficients for wireless power amplifiers

, 2011
In this paper, the general formulas which relate the analytical expression for the fundamental frequency signal and the in-band distortion components to the order of a power amplifier (PA) polynomial modelare derived.

Inherent MS-cleavability of diazirine photo-cross-links enables residue-level structural analysis

Nature Communications
Cross-linking mass spectrometry (XL-MS) is a powerful tool for probing protein structures and protein-protein interactions. While chemical cross-linkers target specific residues with defined chemistry, photo-cross-linkers offer superior reactivity but ...

Robust Optimal Control for a Consumption-investment Problem [PDF]

We give an explicit PDE characterization for the solution of the problem of maximizing the utility of both terminal wealth and intertemporal consumption under model uncertainty.

Abundance Pattern Fitting with Bayesian Inference: Constraining First Stars’ Properties and Their Explosion Mechanism with Extremely Metal-poor Stars

The Astrophysical Journal
The abundance patterns of extremely metal-poor stars preserve a fossil record of the Universe’s earliest chemical enrichment by the supernova explosions from the evolution of first generation of stars, also referred to as Population III stars.
