Meta-Analysis Support
Advanced statistical meta-analysis support: effect size calculation, random-effects pooling models in R metafor, heterogeneity testing, and funnel plots.
Academic Integrity
100% legitimate research advisory and methodological consultation.
Elevate Your Research with Methodological Rigor
When multiple empirical studies address identical research questions using quantitative metrics, an evidence-based conclusion requires more than qualitative comparison. A meta-analysis mathematically combines effect sizes from disparate studies, increasing statistical power and resolving conflicting findings.
Stalynus Research provides specialized statistical consulting for researchers executing quantitative meta-analyses across clinical medicine, psychology, education, and economics. We handle complex effect size transformations, random-effects pooling models, subgroup meta-regressions, and publication bias diagnostics using R (metafor, dmetar), Stata, and RevMan.
What This Service Includes
A systematic, multi-faceted consultation package designed to address your exact research requirements.
Effect Size Computation & Standardization
Converting disparate outcome metrics into standardized effect sizes: Cohen's d, Hedges' g, odds ratios (OR), relative risks (RR), and correlation coefficients (r).
Fixed & Random-Effects Pooling Models
Selecting and justifying appropriate weighting models (DerSimonian-Laird, restricted maximum likelihood - REML, Knapp-Hartung adjustments).
Forest Plot Generation
Creating publication-grade forest plots displaying individual study effects, confidence intervals, and cumulative summary polygons.
Heterogeneity Diagnostics
Quantifying between-study variability via Cochran's Q test, I-squared (I²), and tau-squared (τ²) statistics.
Meta-Regression & Subgroup Analysis
Identifying moderating variables explaining cross-study heterogeneity using multi-variable meta-regression models.
Publication Bias Auditing
Generating funnel plots, performing Egger's linear regression test, Begg's rank test, and Duval and Tweedie's trim-and-fill procedure.
Methodological Precision & Ethical Mentorship
Meta-analysis requires both clinical/subject expertise and advanced statistical rigor. Our quantitative specialists assist you from the moment raw data is extracted from primary papers into structured spreadsheets. We audit effect size calculations, handle correlated outcomes from multi-arm trials, test for influential outlier studies, and provide fully reproducible R or Stata scripts.
We strictly enforce scholarly integrity across all consultations. Our advisory is designed to expand your research capabilities, clarify theoretical obscurities, and equip you with the empirical evidence needed to stand before your doctoral committee or journal peer reviewers with supreme confidence.
