Power of a randomization test in a single case multiple baseline AB design. [PDF]

open access: yesPLoS ONE, 2020
A randomization test can be used to statistically test hypotheses in multiple baseline designs to complement the commonly used visual inspection analysis. A crossed factor simulation study was performed to investigate the power of a randomization test in

Using the global randomization test as a Mendelian randomization falsification test for the exclusion restriction assumption. [PDF]

open access: yesEur J Epidemiol
Mendelian randomization may give biased causal estimates if the instrument affects the outcome not solely via the exposure of interest (violating the exclusion restriction assumption).

A Conditional Randomization Test to Account for Covariate Imbalance in Randomized Experiments [PDF]

open access: yesJournal of Causal Inference, 2016
We consider the conditional randomization test as a way to account for covariate imbalance in randomized experiments. The test accounts for covariate imbalance by comparing the observed test statistic to the null distribution of the test statistic ...

Assessing allocation bias in stratified clinical trials with multi-component endpoints evaluated using the stratified Wei-Lachin test. [PDF]

open access: yesPLoS ONE
BackgroundA common issue in rare disease stratified clinical trials with multi-component endpoints is allocation bias, as they frequently lack blinding.

Randomization across breeding cohorts improves the accuracy of conventional and genomic selection [PDF]

open access: yesThe Plant Genome
Breeding programs conventionally evaluate cohorts in separate trials; however, environmental differences across testing areas can be confounded with genetic differences between cohorts, potentially reducing the accuracy of breeding value estimation.

What is a Randomization Test? [PDF]

open access: yesJournal of the American Statistical Association, 2022
The meaning of randomization tests has become obscure in statistics education and practice over the last century. This article makes a fresh attempt at rectifying this core concept of statistics.

An approximate randomization test for the high-dimensional two-sample Behrens–Fisher problem under arbitrary covariances [PDF]

open access: yesBiometrika, 2021
This paper is concerned with the problem of comparing the population means of two groups of independent observations. An approximate randomization test procedure based on the test statistic of? is proposed.

Comparison of Seven Non-Linear Mixed Effect Model-Based Approaches to Test for Treatment Effect

open access: yesPharmaceutics, 2023
Analyses of longitudinal data with non-linear mixed-effects models (NLMEM) are typically associated with high power, but sometimes at the cost of inflated type I error.

Leveraging the Fisher randomization test using confidence distributions: Inference, combination and fusion learning [PDF]

open access: yesJournal of the Royal Statistical Society: Series B (Statistical Methodology), 2020
The flexibility and wide applicability of the Fisher randomization test (FRT) make it an attractive tool for assessment of causal effects of interventions from modern‐day randomized experiments that are increasing in size and complexity.
