Targeted smoothing parameter selection for estimating average causal effects

, 2013
The non-parametric estimation of average causal effects in observational studies often relies on controlling for confounding covariates through smoothing regression methods such as kernel, splines or local polynomial regression.

Continuous Data Assimilation for a 2D B\'enard Convection System through Horizontal Velocity Measurements Alone

, 2016
In this paper we propose a continuous data assimilation (downscaling) algorithm for a two-dimensional B\'enard convection problem. Specifically we consider the two-dimensional Boussinesq system of a layer of incompressible fluid between two solid ...

SPATIAL DEPENDENCE IN OPTION OBSERVATION ERRORS

Econometric Theory, 2020
In this paper, we develop the first formal nonparametric test for whether the observation errors in option panels display spatial dependence. The panel consists of options with different strikes and tenors written on a given underlying asset. The asymptotic design is of the infill type—the mesh of the strike grid for the observed options shrinks ...

Modeling and Analysis Generic Interface for eXternal numerical codes (MAGIX)

, 2012
The modeling and analysis generic interface for external numerical codes (MAGIX) is a model optimizer developed under the framework of the coherent set of astrophysical tools for spectroscopy (CATS) project.

Continuous Data Assimilation with Stochastically Noisy Data [PDF]

, 2014
We analyze the performance of a data-assimilation algorithm based on a linear feedback control when used with observational data that contains measurement errors.

Pooled error variance and covariance estimation of sparse in situ soil moisture sensor measurements in agricultural fields in Flanders [PDF]

SOIL
Accurately quantifying errors in soil moisture measurements from in situ sensors at fixed locations is essential for reliable state and parameter estimation in probabilistic soil hydrological modeling. This quantification becomes particularly challenging

Sensitivity Analysis for Multiple Comparisons in Matched Observational Studies through Quadratically Constrained Linear Programming

, 2015
A sensitivity analysis in an observational study assesses the robustness of significant findings to unmeasured confounding. While sensitivity analyses in matched observational studies have been well addressed when there is a single outcome variable ...

A High Throughput Workflow Environment for Cosmological Simulations [PDF]

, 2012
The next generation of wide-area sky surveys offer the power to place extremely precise constraints on cosmological parameters and to test the source of cosmic acceleration.
