Effective Degrees of Freedom for Balanced Repeated Replication and Paired Jackknife Variance Estimates: A Unified Approach via Stratum Contrasts
Matthias von Davier
Balanced repeated replication (BRR) and the jackknife are two widely used methods for estimating variances in stratified samples with two primary sampling units per stratum. While…
A Corrected Welch Satterthwaite Equation. And: What You Always Wanted to Know About Kish's Effective Sample but Were Afraid to Ask
Matthias von Davier
This article presents a corrected version of the Satterthwaite (1941, 1946) approximation for the degrees of freedom of a weighted sum of independent variance components. The origi…
An Improved Satterthwaite Effective Degrees of Freedom Correction for Weighted Syntheses of Variance
Matthias von Davier
This article presents an improved approximation for the effective degrees of freedom in the Satterthwaite (1941, 1946) method which estimates the distribution of a weighted combina…
A Modified Satterthwaite (1941,1946) Effective Degrees of Freedom Approximation
Matthias von Davier
This study introduces a correction to the approximation of effective degrees of freedom as proposed by Satterthwaite (1941, 1946), specifically addressing scenarios where component…
Automated Scoring of Graphical Open-Ended Responses Using Artificial Neural Networks
Matthias von Davier, Lillian Tyack, Lale Khorramdel
Automated scoring of free drawings or images as responses has yet to be utilized in large-scale assessments of student achievement. In this study, we propose artificial neural netw…
Training Optimus Prime, M.D.: Generating Medical Certification Items by Fine-Tuning OpenAI's gpt2 Transformer Model
Matthias von Davier
This article describes new results of an application using transformer-based language models to automated item generation (AIG), an area of ongoing interest in the domain of certif…
