specr: Utilities for Specification Curve and Multiverse Analyses

specr provides utilities for conducting and visualizing specification curve analyses (Simonsohn, Simmons & Nelson, 2020) and multiverse analyses (Steegen, Tuerlinckx, Gelman & Vanpaemel, 2016). The package includes functions to setup, run, evaluate, and plot all specifications. It was authored by Philipp K. Masur of the Science Communication Institute.

Use Cases

• Conducting sensitivity analysis for regression models based on specification curve methodology
• Visualizing the results of multiverse analyses based on plotting functions
• Evaluating the robustness of research findings based on systematic exploration of analytical choices

Strengths

• Implements established methodologies from peer-reviewed publications (Simonsohn et al., 2020; Steegen et al., 2016)
• Provides a unified workflow for setup, execution, evaluation, and visualization of analyses

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download
• Column-level documentation is absent; field semantics must be inferred after download
