The Pitman comparison of unbiased linear estimators
The canonical form for the comparison of certain linear estimators using Pitman's Measure of Closeness is generalized to the class of all linear estimators.

Ranked set sampling is a cost efficient sampling technique when actually measuring sampling units is difficult but ranking them is relatively easy. For a family of symmetric location-scale distributions with known location parameter, we consider a best ...

American Journal of Agricultural Economics, EarlyView.Abstract Our general interest is in global trade loss from livestock pathogens, specifically exports. We adopt a causal inference approach that considers animal disease outbreaks over time as non‐staggered binary treatments with the potential for switching in (infection) and out of treatment (recovery) within the sample period. The outcome evolution of

Improving access to new technologies: An experiment with Kenyan input sellers
American Journal of Agricultural Economics, EarlyView.Abstract Agrodealers play a critical role in rural economies, selling essential inputs for agricultural production, stocking new products, and providing farmers with technical advice. However, uncertainty can discourage them from stocking newer, less familiar products, limiting the availability of innovative technologies and leading to market failures ...

Adaptation of a Fluorogenic RNA to N1‐Methylpseudouridine Nucleoside Chemistry
Angewandte Chemie, EarlyView.Several green‐emitting fluorogenic RNA aptamers were evaluated following the replacement of every uridine by N1‐methylpseudouridine (mΨ). Because this modification impaired the function of most aptamers, a directed evolution strategy combining droplet microfluidics, bioinformatics, and rational design was used to identify an aptamer preserving its ...

MEAN SQUARED ERRORS OF SMALL AREA ESTIMATORS UNDER A UNIT-LEVEL MULTIVARIATE MODEL [PDF]
This work deals with estimating the vector of means of characteristics of small areas. In this context, a unit level multivariate model with correlated sampling errors is considered.

American Journal of Botany, EarlyView.Abstract Premise Cuscuta (dodders) consists of ~200 species circumscribed into four subgenera (Monogynella, Cuscuta, Pachystigma, and Grammica) and is the only parasitic genus in Convolvulaceae (the morning‐glory family). This group shows a significant diversity in plastid functionality and represents a rare mixotrophic system among parasitic plants ...

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.ABSTRACT Arthrogryposis multiplex congenita (AMC) is a group of rare congenital conditions, characterized by multiple joint contractures but may involve any body system including central nervous system. AMC is etiologically heterogeneous, with over 400 genetic and many non‐genetic causes implicated in its prenatal development.

Best linear unbiased estimator of the molecular genetic distance between inbred lines
, 1997 International audienceThis paper deals with the statistical properties of the molecular genetic distance between two inbred lines. It is shown that, conditionally on genetic map data, relatedness between inbred lines induces correlations between distance

Translation and Cross‐Cultural Adaptation of the Chronic Rhinosinusitis Control Test for Global Use
International Forum of Allergy &Rhinology, EarlyView.ABSTRACT Introduction The Chronic Rhinosinusitis Control Test (CRCT) is a patient‐reported outcome measure (PROM) written in English that is psychometrically validated to measure chronic rhinosinusitis control. Because the availability of translated PROMs is a driver of data equity—collection of data that is fair and generally representative—our ...
