Changing Oar Rotation Axis Position Increases Catch Angle During Indoor and In-Field Para-Rowing: A Randomized Crossover Trial Verified by a Repeated Measurement Trial

open access: yesFrontiers in Physiology, 2022
A long rowing stroke length is crucial for adequate rowing performance. Therefore, the relocation of the oar from traditional “in front” (NORM) to “behind the rotation axis” (GATE) may increase (para) rowing performance. Thus, 15 able-bodied rowers (21.4

Measuring statistical evidence and multiple testing

open access: yesFACETS, 2018
The measurement of statistical evidence is of considerable current interest in fields where statistical criteria are used to determine knowledge. The most commonly used approach to measuring such evidence is through the use of p-values, even though these

A Bayesian Approach to Measurement of Backtest Overfitting

open access: yesRisks, 2021
Quantitative investment strategies are often selected from a broad class of candidate models estimated and tested on historical data. Standard statistical techniques to prevent model overfitting such as out-sample backtesting turn out to be unreliable in

Development and Validation of Confirmatory Foot-and-Mouth Disease Virus Antibody ELISAs to Identify Infected Animals in Vaccinated Populations

open access: yesViruses, 2021
In foot-and-mouth disease (FMD)-endemic countries, vaccination is commonly used to control the disease, whilst in FMD-free countries, vaccination is considered as an option, in addition to culling the infected and in contact animals.

Testing of breakdates in agricultural prices of selected representatives of animal production

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2012
This paper deals with an investigation of breakdates in agricultural prices. A structural break has occurred if at least one of the model parameters has changed at some date. This date is a breakdate. Ignoring structural breaks in time series can lead to

Simultaneous Inference for High-Dimensional Approximate Factor Model

open access: yesEntropy, 2020
This paper studies simultaneous inference for factor loadings in the approximate factor model. We propose a test statistic based on the maximum discrepancy measure.

CSF testing for multiple sclerosis [PDF]

open access: yesThe Lancet Neurology, 2005
New diagnostic criteria for multiple sclerosis (MS) were published in 2001 by McDonald and colleagues. These criteria take account of the clinical features, brain and spinal-cord MRI findings, CSF findings, and visual evoked-potential studies. The McDonald criteria define rigorous MRI requirements but do not define an optimum CSF test for the diagnosis

Replication data for: Control of the Mean Number of False Discoveries, Bonferroni, and Stability of Multiple Testing

open access: yes, 2007
The Bonferroni multiple testing procedure is commonly perceived as being overly conservative in large-scale simultaneous testing situations such as those that arise in microarray data analysis.

Incorporating Phylogenetic Information in Microbiome Differential Abundance Studies Has No Effect on Detection Power and FDR Control

open access: yesFrontiers in Microbiology, 2020
We consider the problem of incorporating evolutionary information (e.g., taxonomic or phylogenic trees) in the context of metagenomics differential analysis. Recent results published in the literature propose different ways to leverage the tree structure

Controllable testing from nondeterministic finite state machines with multiple ports

open access: yes, 2011
Copyright @ 2011 IEEESome systems have physically distributed interfaces, called ports, at which they interact with their environment. We place a tester at each port and if the testers cannot directly communicate and there is no global clock then we are ...
