Rate and Shape of Functional Decline in Amyotrophic Lateral Sclerosis Identify Clinically Distinct Amyotrophic Lateral Sclerosis Phenotypes

Annals of Neurology, EarlyView.
Objective The ALS Functional Rating Scale–Revised decline rate compresses trajectory shape into a single number, potentially missing distinct phenotypes. We tested whether shape identifies phenotypes that rate does not distinguish, and whether post‐hoc analysis recovers a hidden ultrarapid subgroup. Methods From the Piemonte and Valle d'Aosta register (

Nonparametric Bayesian dictionary learning algorithm based on structural similarity

Tongxin xuebao, 2019
Though nonparametric Bayesian methods possesses significant superiority with respect to traditional comprehensive dictionary learning methods,there is room for improvement of this method as it needs more consideration over the structural similarity and ...

Bayesian Geoadditive Seemingly Unrelated Regression [PDF]

, 2002
Parametric seemingly unrelated regression (SUR) models are a common tool for multivariate regression analysis when error variables are reasonably correlated, so that separate univariate analysis may result in inefficient estimates of covariate effects. A

Effects of Dietary Mannan Oligosaccharides on Growth, Disease Resistance, and Gut Microbiota in Zebrafish

Animal Research and One Health, EarlyView.
Supplementation with mannan oligosaccharides (MOS) enhances growth, disease resistance, antioxidant capacity, and gut microbiota diversity while suppressing inflammation, apoptosis, and strengthening intestinal barrier integrity in zebrafish challenged with LPS or DSS.

Untangling sample and population level estimands in Bayesian causal computation

Journal of Causal Inference
Model-based Bayesian inference for sample and population-level causal estimands has been growing in popularity. This literature routinely emphasizes clear specification of the target estimand, however blind implementation of standard computational ...

pyrichlet: A Python Package for Density Estimation and Clustering Using Gaussian Mixture Models

Journal of Statistical Software
Bayesian nonparametric models have proven to be successful tools for clustering and density estimation. While there exists a nourished ecosystem of implementations in R, for Python there are only a few. Here we develop a Python package called pyrichlet,

A Bayesian nonparametric method for prediction in EST analysis

BMC Bioinformatics, 2007
Background Expressed sequence tags (ESTs) analyses are a fundamental tool for gene identification in organisms. Given a preliminary EST sample from a certain library, several statistical prediction problems arise.

Quantile pyramids for Bayesian nonparametrics [PDF]

, 2009
Polya trees fix partitions and use random probabilities in order to construct random probability measures. With quantile pyramids we instead fix probabilities and use random partitions.

Population pharmacokinetics of levetiracetam in term neonates with hypoxic–ischemic encephalopathy and therapeutic hypothermia: The LEVNEONAT‐1 study

British Journal of Clinical Pharmacology, EarlyView.
Aim This study aimed to describe the pharmacokinetics (PK) of levetiracetam (LEV) in term neonates treated for neonatal seizures secondary to hypoxic–ischemic encephalopathy (HIE). Methods Fifteen neonates were included and received a loading dose ranging from 30 to 60 mg/kg followed by eight maintenance doses corresponding to one‐fourth of the loading
