trackdown: collaborative writing and editing your R Markdown and Sweave documents in Google Drive

The advantages of using literate programming that combines plain-text and code chunks (e.g., R Markdown and Sweave) are well recognized. This allows the creation of rich, high quality, and reproducible documents. However, collaborative writing and …

Enhancing Statistical Inference via Prospective and Retrospective Design Analysis

Traditional power analysis has a narrow focus on statistical significance, overlooking other related inferential risks concerning estimates uncertainty under hypothetical replications of a study. To evaluate inferential risks related to effect size …

PRDA package: Enhancing Statistical Inference via Prospective and Retrospective Design Analysis.

We introduce the PRDA (Prospective and Retrospective Design Analysis) R-package that allows researchers to perform a “Design Analysis” under different experimental scenarios (Altoè et al., 2020). Considering a plausible effect size (or its prior distribution), researchers can evaluate either the inferential risks for a given sample size or the required sample size to obtain a given statistical power. The main aim of PRDA package is to enhance researcher reasoning about inferential risks avoiding automated decisions.
