Food Safety and Health, EarlyView.Planned harvesting and processing of marine macroalgae could meet future global food needs and mitigate fuel‐originated carbon dioxide responsible for climate change. Microalgal foods are nutritious and safe. The utilization of macroalgae would avoid environmental problems arising from the release of overgrowing macroalgae caused by heatwaves, which ...

Hypothesis Testing in the Presence of One-sided Nuisance Parameters [PDF]
In this paper, we investigate whether similar improvements are observed when we have a non-sample information regarding the nuisance parameters in the testing problem.

Health Economics, EarlyView.ABSTRACT Even though data on hospital admissions are widely used in health research, hospitalization‐related estimands measured using these data are not always clearly conceptualized. Consequently, estimators of these quantities can have unclear rationales and undesirable properties.

A conditional Bayesian approach for testing independence in two-way contingency tables
Kuwait Journal of Science, 2013 Bayesian methods for exact small-sample analysis with categorical data in contingency tables are considered. Point null hypotheses versus two-sided hypothesis are tested concerning log odds ratios in these tables with fixed row margins. The conditional

On the use of the BMC to resolve Bayesian inference with nuisance parameters
EPJ Nuclear Sciences & Technologies, 2018 Nuclear data are widely used in many research fields. In particular, neutron-induced reaction cross sections play a major role in safety and criticality assessment of nuclear technology for existing power reactors and future nuclear systems as in ...

Motive and Opportunity: Order Choice in a Limit Order Book With Dispersed Information
International Journal of Finance &Economics, EarlyView.ABSTRACT We test predictions of market microstructure theory relating to the determinants of order choice in a limit order book where information is dispersed among traders. Using an experimental limit order book, with a large state space, we find that informed traders exhibit patience, compatible with the ‘waiting game’ behaviour described in Foster ...

iNew Medicine, EarlyView.ABSTRACT Behavioral and psychological symptoms of dementia (BPSD) are highly prevalent in Alzheimer's disease (AD), but the underlying mechanisms are unclear. This study aims to elucidate the neuropathological mechanisms underlying BPSD by investigating gray matter volume (GMV) and brain connectivity in AD patients with and without BPSD.

On the Nuisance Parameter Elimination Principle in Hypothesis Testing
EntropyThe Non-Informative Nuisance Parameter Principle concerns the problem of how inferences about a parameter of interest should be made in the presence of nuisance parameters. The principle is examined in the context of the hypothesis testing problem.

P Values and Nuisance Parameters
, 2008 We review the de nition and interpretation of p values, describe methods to incorporate systematic uncertainties in their calculation, and brie y discuss a non-regular but common problem caused by nuisance parameters that are unidenti ed under the null ...

Revisiting EWMA in High‐Frequency‐Based Portfolio Optimization: A Comparative Assessment
Journal of Applied Econometrics, EarlyView.ABSTRACT This paper compares the statistical and economic performance of state‐of‐the‐art high‐frequency (HF) based multivariate volatility models with a simpler, widely used alternative, the Exponentially Weighted Moving Average (EWMA) filter. Using over two decades of 100 U.S.
