Factors associated with risk of developmental delay in preschool children in a setting with high rates of malnutrition: a cross-sectional analysis of data from the IHOPE study, Madagascar

open access: yesBMC Pediatrics, 2020
Background 50% of Malagasy children have moderate to severe stunting. In 2016, a new 10 year National Nutrition Action Plan (PNAN III) was initiated to help address stunting and developmental delay. We report factors associated with risk of developmental

Accuracy of tree stem circumference estimation using close range photogrammetry: Does point-based stem disk thickness matter?

open access: yesTrees, Forests and People, 2020
There is an increase in the use of photogrammetric point clouds for tree attribute mensuration. Stem diameter and circumference can be estimated from point clouds using stem disks of varying thicknesses along the bole.

Les transferts monétaires des migrants : pays industrialisés et pays en développement

open access: yesRevue Européenne des Migrations Internationales, 2006
Migrants’ remittances. Comparing industrial and developing countries. Remittances are a challenge for developing countries. Since it impossible to provide exact figures of informal transfers, although they are probably very large, only official money ...

On subset least squares estimation and prediction in vector autoregressive models with exogenous variables

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract We establish the consistency and the asymptotic distribution of the least squares estimators of the coefficients of a subset vector autoregressive process with exogenous variables (VARX). Using a martingale central limit theorem, we derive the asymptotic normal distribution of the estimators. Diagnostic checking is discussed using kernel‐based

The emergence of French statistics. How mathematics entered the world of statistics in France during the 1920s [PDF]

open access: yes, 2011
This paper concerns the emergence of modern mathematical statistics in France after the First World War. Emile Borel's achievements are presented, and especially his creation of two institutions where mathematical statistics was developed: the {\it ...

Fluctuations in the level density of a Fermi gas [PDF]

open access: yes, 2004
We present a theory that accurately describes the counting of excited states of a noninteracting fermionic gas. At high excitation energies the results reproduce Bethe's theory. At low energies oscillatory corrections to the many--body density of states,

Asymptotic properties of cross‐classified sampling designs

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract We investigate the family of cross‐classified sampling designs across an arbitrary number of dimensions. We introduce a variance decomposition that enables the derivation of general asymptotic properties for these designs and the development of straightforward and asymptotically unbiased variance estimators.
