Confidence intervals for the common coefficient of variation of rainfall in Thailand [PDF]

PeerJ, 2020
The log-normal distribution is often used to analyze environmental data like daily rainfall amounts. The rainfall is of interest in Thailand because high variable climates can lead to periodic water stress and scarcity.

Simultaneous confidence intervals for all pairwise comparisons of the means of delta-lognormal distributions with application to rainfall data.

PLoS ONE, 2021
Natural disasters such as flooding and landslides are important unexpected events during the rainy season in Thailand, and how to direct action to avoid their impacts is the motivation behind this study.

Estimation of prediction error variances via Monte Carlo sampling methods using different formulations of the prediction error variance [PDF]

, 2009
peer-reviewedCalculation of the exact prediction error variance covariance matrix is often computationally too demanding, which limits its application in REML algorithms, the calculation of accuracies of estimated breeding values and the control of ...

Recovery-informed Theory: Situating the Subjective in the Science of Substance Use Disorder Recovery [PDF]

, 2019
As recovery from substance use disorder becomes more than a mere quantifiable outcome, there exists a need to discuss and propose the underlying theoretical constructs that ultimately describe and identify the science of recovery.
