An Improved Sample-Aggregation Method for Weibull Estimation of Bushing Maximum Friction Torque Under Small-Sample Conditions

open access: yesAerospace
This study addresses the instability of statistical modeling for small-sample maximum friction torque data under multiple temperature conditions. Within the Weibull distribution framework, a sample-aggregation method is proposed, and a unified modeling ...

Speeding Up Non-Parametric Bootstrap Computations for Statistics Based on Sample Moments in Small/Moderate Sample Size Applications. [PDF]

open access: yesPLoS ONE, 2015
In this paper we propose a vectorized implementation of the non-parametric bootstrap for statistics based on sample moments. Basically, we adopt the multinomial sampling formulation of the non-parametric bootstrap, and compute bootstrap replications of ...

Recalibrating single-study effect sizes using hierarchical Bayesian models

open access: yesFrontiers in Neuroimaging, 2023
IntroductionThere are growing concerns about commonly inflated effect sizes in small neuroimaging studies, yet no study has addressed recalibrating effect size estimates for small samples. To tackle this issue, we propose a hierarchical Bayesian model to

Small size sampling

open access: yesInternational Journal of Basic & Clinical Pharmacology, 2012
Though small size samples can be planned and justified based on scarcity of time, money and manpower, there are situations making more accuracy a must and needing larger samples sizes. That’s why rare adverse drug reactions are identified only after a drug comes into the market and a large population is exposed to it.

Why sample size estimates? [PDF]

open access: yes, 2018
Sample size estimates are critical to the planning and interpretation of clinical studies, whether they are descriptive or analytical. Too small a sample size will result in imprecise estimates in a descriptive study and failure to achieve ’statistical ...

Prediction method of pipeline corrosion depth based on the correlation and Bayesian inference

open access: yesYou-qi chuyun, 2021
The number of samples for detecting corrosion characteristic value is difficult to reach a large enough size in practical engineering, which leads to the pipeline corrosion evaluation results tend to be aggressive.

Addressing the sample size problem in behavioural operational research: Simulating the newsvendor problem [PDF]

open access: yes, 2016
Laboratory-based experimental studies with human participants are beneficial for testing hypotheses in behavioural operational research. However, such experiments are not without their problems. One specific problem is obtaining a sufficient sample size,
