Beyond the Metrics: Context‐Aware Calibration for Better Drain Flow Modelling

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT Robust hydrological and water quality modelling is essential for advancing the understanding and management of engineered agricultural subsurface drainage systems. Achieving credible model output hinges on calibration strategies that are both rigorous and context sensitive. At the field scale, accurately capturing the dynamics of nutrient load

Joint Estimation and Bandwidth Selection in Partially Parametric Models

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT We propose a single‐step approach to estimating a model with both a known nonlinear parametric component and an unknown nonparametric component. We study the large sample behavior of a simultaneous optimization routine that estimates both the parameter vector of the parametric component and the bandwidth vector used to smooth the unknown ...

A Consistent Heteroskedasticity‐Robust LM‐Type Specification Test for Semiparametric Models

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT This article develops a heteroskedasticity‐robust Lagrange Multiplier‐type specification test for semiparametric regression models. The test is able to detect a wide class of deviations from the null hypothesis. The test statistic is based on the estimates from the restricted semiparametric model, can be computed in a regression‐based way, and

Count Data Models With Heterogeneous Peer Effects Under Rational Expectations

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT This paper develops a peer effect model for count responses under rational expectations. The model accounts for heterogeneity in peer effects across groups based on observed characteristics. Identification is based on the linear model condition that requires the presence of friends of friends who are not direct friends.

Optimizing Detection Schemes for Broadband Pump‐Probe Microscopy

open access: yesMicroscopy Research and Technique, EarlyView.
Small spot sizes and broadband spectral coverage create unusual noise challenges for broadband pump‐probe microscopy. Analysis of probe and detector noise characteristics can provide strategies for mitigating these challenges. ABSTRACT Although similar to more commonly implemented single wavelength approaches, broadband pump‐probe or transient ...
