Consilience of methods for phylogenetic analysis of variance. [PDF]

open access: yesEvolution, 2022
Simulation‐based and permutation‐based inferential methods are commonplace in phylogenetic comparative methods, especially as evolutionary data have become more complex and parametric methods more limited for their analysis. Both approaches simulate many

Wavelet analysis of variance box plot. [PDF]

open access: yesJ Appl Stat, 2022
Functional box plots satisfy two needs; visualization of functional data, and the calculation of important box plot statistics. Data visualization illuminates key characteristics of functional sets missed by statistical tests and summary statistics.

An Improved Analysis of (Variance-Reduced) Policy Gradient and Natural Policy Gradient Methods [PDF]

open access: yesNeural Information Processing Systems, 2022
In this paper, we revisit and improve the convergence of policy gradient (PG), natural PG (NPG) methods, and their variance-reduced variants, under general smooth policy parametrizations.

Data transformation in biological assays

open access: yesPesquisa Florestal Brasileira, 2021
The analysis of variance is the statistical test most used for comparison of three or more means simultaneously. Its application requires, however, the compliance to some assumptions, with main emphasis on normality of the data and homoscedasticity of ...

Simulation-Based Power Analysis for Factorial Analysis of Variance Designs

open access: yesAdvances in Methods and Practices in Psychological Science, 2021
Researchers often rely on analysis of variance (ANOVA) when they report results of experiments. To ensure that a study is adequately powered to yield informative results with an ANOVA, researchers can perform an a priori power analysis.
