Joint Estimation and Bandwidth Selection in Partially Parametric Models

Journal 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 ...

Count Data Models With Heterogeneous Peer Effects Under Rational Expectations

Journal 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.

Subsquares in Random Latin Squares and Rectangles

Journal of Combinatorial Designs, EarlyView.
ABSTRACT A k×n $k\times n$ partial Latin rectangle is C‐sparse $C \mbox{-} \mathrm{sparse}$ if the number of nonempty entries in each row and column is at most C $C$ and each symbol is used at most C $C$ times. We prove that the probability a uniformly random k×n $k\times n$ Latin rectangle, where k<(1∕2−α)n $k\lt (1\unicode{x02215}2-\alpha )n ...

Utilising Benford's Law in the Validation of Precipitation Datasets

International Journal of Climatology, EarlyView.
This study demonstrates Benford's Law as a robust diagnostic tool for precipitation data integrity. Global monthly precipitation consistently conforms to the law, regardless of origin, while regional data requires appropriate temporal granularity for adherence.

A Continental United States Climatology of Precipitation Whiplash Using a New Event‐Based Definition

International Journal of Climatology, EarlyView.
Precipitation whiplash events have been increasingly studied over the recent decade, however, no studies have considered the spatial coherence of grid points in their examination. Therefore, we developed an algorithm that defines spatially coherent precipitation whiplash events on the subseasonal‐to‐seasonal timescale between 1915 and 2020 which can be
