Zero-inflated Probability Models and Their Applications to the Analysis of Test Scores

Kodo Keiryogaku (The Japanese Journal of Behaviormetrics), 2009
Statistical analysis of the number of correct answers of a test consisting of n items will be considered in this article. A beta-binomial distribution is assumed to the model of the distribution of test scores in this article. For such test scores, the situation of extra zeros sometimes arises in practical applications.

Large‐scale bidirectional arrayed genetic screens identify OXR1 and EMC4 as modifiers of αSynuclein aggregation

FEBS Open Bio, EarlyView.
Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

Zero-inflated quantile rank-score based test (ZIQRank) with application to scRNA-seq differential gene expression analysis

The Annals of Applied Statistics, 2021
Differential gene expression analysis based on scRNA-seq data is challenging due to two unique characteristics of scRNA-seq data. First, multimodality and other heterogeneity of the gene expression among different cell conditions lead to divergences in the tail events or crossings of the expression distributions. Second, scRNA-seq data generally have a

Real‐World Performance of CSF Kappa Free Light Chains in the 2024 McDonald Criteria

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Kappa free light chains (KFLCs) in the cerebrospinal fluid (CSF) have a similar performance to CSF‐restricted oligoclonal bands (OCB) for multiple sclerosis (MS) diagnosis. To help with implementation, we set out to resolve several remaining uncertainties: (1) performance in a real‐world cohort and the 2024 McDonald criteria; (2 ...

The Source of Lake Wobegon

Nonpartisan Education Review, 2005
John J. Cannell's late 1980's “Lake Wobegon” reports suggested widespread deliberate educator manipulation of norm-referenced standardized test (NRT) administrations and results, resulting in artificial test score gains.

Improvement in national test reading scores at Key Stage 1; grade inflation or better achievement? [PDF]

British Educational Research Journal, 2007
The aim of the UK National Literacy Strategy is to raise standards in literacy. Strong evidence for its success has, however, been lacking: most of the available data comes from performance on tests administered in schools or from Office for Standards in Education reports and is vulnerable to suggestions of bias.

Development of a Prediction Model for Progression Risk in High‐Grade Gliomas Based on Habitat Radiomics and Pathomics

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To investigate the value of constructing models based on habitat radiomics and pathomics for predicting the risk of progression in high‐grade gliomas. Methods This study conducted a retrospective analysis of preoperative magnetic resonance (MR) images and pathological sections from 72 patients diagnosed with high‐grade gliomas (52 ...

Predicting Inflation: Professional Experts Versus No-Change Forecasts [PDF]

, 2010
We compare forecasts of United States inflation from the Survey of Professional Forecasters (SPF) to predictions made by simple statistical techniques. In nowcasting, economic expertise is persuasive. When projecting beyond the current quarter, novel yet

An analysis of involuntary excess reserves, monetary policy and risk-taking behaviour of Chinese banks [PDF]

, 2015
In this paper, we examine the effects of monetary policy on the risk-taking behaviour of Chinese banks in the presence of involuntary excess reserves based on a sample of 95 banks.
