Classical Conditioning for Pain: The Development of a Customized Single-Case Experimental Design

open access: yesJournal of Trial and Error, 2022
Single-case experiments are increasingly popular in the behavioral sciences. Due to their flexibility, single-case designs can be customized to test a variety of experimental hypotheses.

Randomized Quasi-Random Testing [PDF]

open access: yesIEEE Transactions on Computers, 2016
Random testing is a fundamental testing technique that can be used to generate test cases for both hardware and software systems. Quasi-random testing was proposed as an enhancement to the cost-effectiveness of random testing: In addition to having similar computation overheads to random testing, it makes use of quasi-random sequences to generate low ...

Log-rank and stratified log-rank tests

open access: yesStatistical Theory and Related Fields, 2023
In randomized clinical trials with right-censored time-to-event outcomes, the popular log-rank test without adjusting for baseline covariates is asymptotically valid for treatment effect under simple randomization of treatments but is too conservative ...

A roadmap to using randomization in clinical trials

open access: yesBMC Medical Research Methodology, 2021
Background Randomization is the foundation of any clinical trial involving treatment comparison. It helps mitigate selection bias, promotes similarity of treatment groups with respect to important known and unknown confounders, and contributes to the ...

Nonparametric Inference for Multivariate Data: The R Package npmv

open access: yesJournal of Statistical Software, 2017
We introduce the R package npmv that performs nonparametric inference for the comparison of multivariate data samples and provides the results in easy-to-understand, but statistically correct, language.

Evaluating Domain Randomization in Deep Reinforcement Learning Locomotion Tasks

open access: yesMathematics, 2023
Domain randomization in the context of Reinforcement learning (RL) involves training RL agents with randomized environmental properties or parameters to improve the generalization capabilities of the resulting agents.

Detection of widespread horizontal pleiotropy in causal relationships inferred from Mendelian randomization between complex traits and diseases

open access: yesNature Genetics, 2018
Horizontal pleiotropy occurs when the variant has an effect on disease outside of its effect on the exposure in Mendelian randomization (MR). Violation of the ‘no horizontal pleiotropy’ assumption can cause severe bias in MR.

rich: An R Package to Analyse Species Richness

open access: yesDiversity, 2011
The paper describes rich, a new R package to perform species richness estimation and comparison. Species richness is the simplest surrogate for the more complex concept of species biodiversity.

Detection of density-dependent effects on caribou numbers from a series of census data

open access: yesRangifer, 1991
The main objective of this paper is to review and discuss the applicability of statistical procedures for the detection of density dependence based on a series of annual or multi-annual censuses.
