Categorical classifiers in multiclass classification with imbalanced datasets

Statistical Analysis and Data Mining: The ASA Data Science Journal, Volume 16, Issue 4, Page 391-405, August 2023., 2023
Abstract This paper discusses, in a multiclass classification setting, the issue of the choice of the so‐called categorical classifier, which is the procedure or criterion that transforms the probabilities produced by a probabilistic classifier into a single category or class.

A new goodness‐of‐fit measure for probit models: Surrogate R2

British Journal of Mathematical and Statistical Psychology, Volume 76, Issue 1, Page 192-210, February 2023., 2023
Abstract Probit models are used extensively for inferential purposes in the social sciences as discrete data are prevalent in a vast body of social studies. Among many accompanying model inference problems, a critical question remains unsettled: how to develop a goodness‐of‐fit measure that resembles the ordinary least square (OLS) R2 used for linear ...

Effects of Mexiletine and Lacosamide on Nerve Excitability in Healthy Subjects: A Randomized, Double‐Blind, Placebo‐Controlled, Crossover Study

Clinical Pharmacology &Therapeutics, Volume 112, Issue 5, Page 1008-1019, November 2022., 2022
Selective voltage‐gated sodium channel blockers are of growing interest as treatment for pain. For drug development of such compounds, it would be critical to have a biomarker that can be used for proof‐of‐mechanism. We aimed to evaluate whether drug‐induced changes in sodium conductance can be detected in the peripheral nerve excitability profile in ...

The Status of De in Romance Indefinites, Partitives and Pseudopartitives*

Studia Linguistica, Volume 76, Issue 1, Page 167-211, April 2022., 2022
Abstract This paper focuses on the status of de in Romance indefinites, partitives and pseudopartitives. It argues that there is neither a ‘partitive article’ nor a ‘partitive preposition’ in syntax. De in Romance indefinites is the overt Spell‐Out of an abstract operator de that cancels the definiteness of articles and is responsible for ...

Fully and Partially Replicated Experimental Designs for Evaluating Intravarietal Variability in Grapevine

Australian Journal of Grape and Wine Research, Volume 2022, Issue 1, 2022., 2022
Background and Aims. In ancient grapevine varieties, the experimental design of field trials is crucial to providing a reliable evaluation of quantitative traits. The main purposes of this study are to demonstrate the benefits of the resolvable row‐column design (RCD) for quantifying intravarietal variability and performing polyclonal selection and to ...
