pwrss: Statistical Power and Sample Size Calculation Tools for Hypothesis Tests

The 'pwrss' R package provides functions for statistical power and minimum required sample size calculations. It is authored by Metin Buluş and is designed for a wide range of commonly used hypothesis tests in psychological, biomedical, and social sciences. The dataset's size, row count, and last update date are unknown.

Use Cases

• Calculate statistical power for a planned study based on the package's functions for hypothesis tests.
• Determine the minimum required sample size for an experiment based on the described power calculation tools.
• Compare power analysis results across different statistical test types supported by the package.
• Support study design and grant proposals with formal power calculations based on the provided statistical methods.

Strengths

• Package is described as providing 'flexible and comprehensive functions' for power and sample size calculations.
• Covers a 'wide range of commonly used hypothesis tests' across multiple scientific domains.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
