SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you combine effect sizes across multiple psychology studies into a single quantitative estimate while also measuring heterogeneity and probing publication bias.

Core Features & Use Cases

  • Effect size computation: Derive Cohen's d and small-sample corrected Hedges' g from common summary statistics (means/SDs and n, t, or F).
  • Random-effects meta-analysis: Perform DerSimonian-Laird pooling and report heterogeneity (Q, I², τ²) with confidence intervals and p-values.
  • Publication bias diagnostics: Run funnel-plot oriented tests and corrections including Egger test, trim-and-fill (mentioned), PET-PEESE regression correction, and p-curve analysis.
  • Visualization & sensitivity: Generate forest plots (with summary diamond) and support downstream robustness checks such as leave-one-out style workflows.

Quick Start

Use the meta-analysis-psych skill to run a random-effects meta-analysis from your study-level dataset and automatically produce the pooled Hedges' g estimate plus heterogeneity and publication-bias outputs.

FAQPage Schema
How do I compute Hedges' g from study summary statistics for a meta-analysis?

To compute Hedges' g for a meta-analysis, derive Cohen's d from common summary statistics like means, standard deviations, and sample sizes, then apply a small-sample correction. This Skill automates that calculation directly from input effect-size and variance columns.

How do I run a random-effects meta-analysis with DerSimonian-Laird pooling in Python?

Running a random-effects meta-analysis with DerSimonian-Laird pooling requires inputting study-level effect sizes and variances. This Skill uses numpy and scipy to calculate pooled estimates, heterogeneity metrics like Q and I², and confidence intervals deterministically.

What is the best way to check publication bias in a psychology meta-analysis?

Checking publication bias in a psychology meta-analysis involves running an Egger test, PET-PEESE regression correction, and p-curve analysis. This Skill performs all these evaluations alongside funnel-plot oriented diagnostics to probe biases across multiple studies.

How do I quantify heterogeneity using I² and τ² in a meta-analysis?

Quantifying heterogeneity using I² and τ² in a meta-analysis is part of the DerSimonian-Laird random-effects pooling process. This Skill calculates these metrics along with the Q statistic and reports them with confidence intervals and p-values.

Can I generate a forest plot with a summary diamond from my study-level dataset?

Yes, you can generate a forest plot with a summary diamond from your study-level dataset. This Skill uses matplotlib to produce visualizations directly from the pooled Hedges' g estimates and heterogeneity computations.

What input data format do I need for a quantitative synthesis of multiple psychology studies?

For a quantitative synthesis of multiple psychology studies, you need a study-level dataset with input effect-size and variance columns. This Skill processes these deterministic computations using pandas data structures to output pooled estimates and statistical tests.
