TLDR
In the new version, procedures to analyze the power of tests based on single-sample tetrachoric correlations, comparisons of dependent correlations, bivariate linear regression, multiple linear regression based on the random predictor model, logistic regression, and Poisson regression are added.
Abstract
G*Power is a free power analysis program for a variety of statistical tests. We present extensions and improvements of the version introduced by Faul, Erdfelder, Lang, and Buchner (2007) in the domain of correlation and regression analyses. In the new version, we have added procedures to analyze the power of tests based on (1) single-sample tetrachoric correlations, (2) comparisons of dependent correlations, (3) bivariate linear regression, (4) multiple linear regression based on the random predictor model, (5) logistic regression, and (6) Poisson regression. We describe these new features and provide a brief introduction to their scope and handling.

Calculating and reporting effect sizes to facilitate cumulative science: a practical primer for t-tests and ANOVAs

TL;DR: A practical primer on how to calculate and report effect sizes for t-tests and ANOVA's such that effect sizes can be used in a-priori power analyses and meta-analyses and a detailed overview of the similarities and differences between within- and between-subjects designs is provided.

Using Bayes to get the most out of non-significant results

TL;DR: It is argued Bayes factors allow theory to be linked to data in a way that overcomes the weaknesses of the other approaches, and provides a coherent approach to determining whether non-significant results support a null hypothesis over a theory, or whether the data are just insensitive.

Repeated Measures Correlation

TL;DR: The R package (rmcorr) is introduced and its use for inferential statistics and visualization with two example datasets are used to illustrate research questions at different levels of analysis, intra-individual, and inter-individual.

Heart Rate Variability and Cardiac Vagal Tone in Psychophysiological Research - Recommendations for Experiment Planning, Data Analysis, and Data Reporting.

TL;DR: This paper will provide psychophysiological researchers with recommendations and practical advice concerning experimental designs, data analysis, and data reporting to ensure that researchers starting a project with HRV and cardiac vagal tone are well informed regarding methodological considerations in order for their findings to contribute to knowledge advancement in their field.

The reliability paradox: Why robust cognitive tasks do not produce reliable individual differences.

TL;DR: The very reason such tasks produce robust and easily replicable experimental effects – low between-participant variability – makes their use as correlational tools problematic, and it is demonstrated that taking reliability estimates into account has the potential to qualitatively change theoretical conclusions.
