Monitoring process variability using auxiliary information [PDF]

Computational Statistics, 2007
A construction of Shewhart-type control charts is considered for the changes of variance of a controlled variable \(Y\) in the case when some auxiliary variable \(X\) is also observed. Bivariate normality of \((X,Y)\) is assumed. The chart is based on a regression-type estimate for the variance of \(Y\) by observations on \(X\). The central line, lower

Improving inference of Gaussian mixtures using auxiliary variables [PDF]

Statistical Analysis and Data Mining: The ASA Data Science Journal, 2015
AbstractExpanding a lower‐dimensional problem to a higher‐dimensional space and then projecting back is often beneficial. This article rigorously investigates this perspective in the context of finite mixture models, specifically how to improve inference for mixture models by using auxiliary variables. Despite the large literature in mixture models and

Safety of Daprodustat for the Treatment of Chronic Kidney Disease Anemia: Final Analysis of a Multicenter Postmarketing Surveillance Study in Japan

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction This final analysis of a multicenter, prospective postmarketing surveillance study evaluated the safety of daprodustat in patients with chronic kidney disease anemia in routine clinical practice in Japan. Methods Patients who initiated daprodustat between September 2020 and July 2022 were registered.

Improved estimator for the estimation of sensitive variable using ORRT models

Research in Statistics
In this study, we concern with the improved estimation of sensitive variable when there is non-response and measurement error on sensitive variable but the auxiliary variable is non sensitive in nature.

Elasto-plastic solution to expansion of a spherical cavity in dilatant sand

Yantu gongcheng xuebao, 2017
The current solutions to spherical cavity expansion can not properly consider the peak strength and dilatancy of the sand, and thus there is some dispency between the solution and the practical situation.

Forecasting the Dialysis Burden in Japan: Validation‐Based Projections of Prevalence and Incidence Through 2050

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.

A Comparative Study of New Ratio-Type Family of Estimators Under Stratified Two-Phase Sampling

Mathematics
Two-phase sampling is a useful technique for sample surveys, particularly when prior auxiliary data is not accessible. The ranks of the auxiliary variable often coincide with those of the research variable when two variables are correlated.

Optimal Neutrosophic Difference to Log-Type Estimator for Population Mean: Some Numerical and Simulation Studieshttps://fs.unm.edu/NSS/11NeutrosophicDifference.pdf [PDF]

Neutrosophic Sets and Systems
Indeterminacy in the data are commonly observed in various fields like biomedicine, finance, marketing and other sphere of sciences, where classical statistical methods is a challenging task to deal such type of data.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Neutrosophic Exponential Ratio-Type Estimator for Finite Population Mean [PDF]

Neutrosophic Sets and Systems
This paper proposes a neutrosophic exponential-type estimator for finite population mean estimation using auxiliary variables. Traditional statistical estimators often fall short when handling vague or uncertain data.
