Cadmium exposure increases the risk of juvenile obesity: a human and zebrafish comparative study

International Journal of Obesity, 42(7), 1285–1295.

MeSH headings : Adipogenesis / drug effects; Animals; Cadmium / adverse effects; Cadmium / analysis; Cadmium / blood; Disease Models, Animal; Environmental Exposure / adverse effects; Environmental Exposure / analysis; Female; Humans; Infant, Newborn; Male; Maternal Exposure / adverse effects; Metals, Heavy / adverse effects; Metals, Heavy / analysis; Pediatric Obesity / blood; Pediatric Obesity / chemically induced; Pediatric Obesity / epidemiology; Pregnancy; Pregnant Women; Prenatal Exposure Delayed Effects / blood; Prenatal Exposure Delayed Effects / chemically induced; Prenatal Exposure Delayed Effects / epidemiology; Prospective Studies; Socioeconomic Factors; United States / epidemiology; Zebrafish / metabolism
TL;DR: The findings identify Cd as a potential human obesogen, suggesting that the underlying mechanisms may be evolutionarily conserved, and that zebrafish may be a valuable model for uncovering pathways leading to Cd-mediated obesity in human populations. (via Semantic Scholar)

On nonparametric estimation of the latent distribution for ordinal data

Computational Statistics & Data Analysis, 119, 86–98.

By: S. Ghosh n, C. Burns*, D. Prager*, L. Zhang* & G. Hui*

author keywords: Anderson Darling statistic; Bernstein polynomials; Quadratic programming; Survey data
TL;DR: A nonparametric model based on mixtures of scaled Beta distributions is presented and estimation is carried out using a version of Anderson–Darling statistic-based criteria which is shown to be computationally more efficient than likelihood based criteria and robust against any underlying continuous distribution.

Bayesian comparative study on binary time series

Journal of Statistical Computation and Simulation, 88(14), 2811–2826.

author keywords: DIC; Jeffreys prior; log-marginal likelihood; misclassification error rate; normal prior; prediction; Student's t prior; 62F15
TL;DR: The results show that the Jeffreys prior perform better in most of the situations for both the simulation and the rainfall data, and among weakly informative priors considered, Student's t prior with 7 degrees of freedom fits the data most adequately. (via Semantic Scholar)
