I am a PhD Statistical Consultant helping researchers, clinical teams, academic authors, and organizations turn complex datasets, uncertain model choices, reviewer concerns, and methodological ambiguity into statistically sound, reproducible, publication-oriented, and decision-relevant results. My work is strongest where the analysis requires more than simply running a standard test. I help align the research question, dataset structure, statistical assumptions, model choice, validation strategy, and final interpretation so the conclusions remain accurate, transparent, and defensible under peer review, supervisor review, or stakeholder scrutiny. Whether you are working on a journal manuscript, doctoral research project, clinical or health-research study, real-world evidence analysis, HEOR/HTA project, econometric evaluation, psychometric validation, or advanced quantitative model, I can help build a structured analytical workflow and translate complex findings into clear, reviewer-ready or decision-focused conclusions. 🎯 DOMAINS I WORK IN • Journal Manuscripts, Doctoral Research, and Publication Support • Clinical & Health Research • Real-World Evidence and Observational Studies • HEOR/HTA and Decision-Relevant Health Evidence • Econometrics & Policy Evaluation • Behavioral, Social Science, Psychometric, and Survey Research 🔬 CORE EXPERTISE • Bayesian Hierarchical Modeling and Evidence Synthesis • Causal Inference for Observational Studies • Survival, Cox, and Competing-Risk Analysis • Longitudinal and Mixed-Effects Modeling • Clinical/RWE Predictive Modeling and Validation • Cost-Effectiveness Analysis, ICER/QALY Interpretation, and Probabilistic Sensitivity Analysis • Latent Profile and Latent Class Analysis (LPA/LCA) • Structural Equation Modeling (SEM/CFA) • Mixture Modeling, Model Selection, Covariates, and Distal Outcomes • Regression, Logistic, Panel, and Econometric Modeling • Monte Carlo Simulation, Robustness Checks, and Statistical Validation ⭐ SELECTED WORK • Completed a 5-star Latent Profile Analysis project with covariates and distal outcomes using R3STEP and BCH-style interpretation, producing publication-ready tables, model-comparison summaries, and reviewer-ready explanations for an academic manuscript. • Developed a reproducible clinical/RWE causal-inference workflow using IPTW, doubly robust AIPW estimation, covariate-balance assessment, overlap diagnostics, and sensitivity analysis for observational mortality data. • Built a transparent HEOR/HTA-style probabilistic cost-effectiveness model using expected costs and QALYs, ICER, net monetary benefit, 10,000 Monte Carlo simulations, scenario analysis, and publication-style figures. • Developed a Bayesian hierarchical evidence-synthesis workflow across 22 clinical trials, including prior-predictive and posterior-predictive checks, convergence diagnostics, heterogeneity assessment, partially pooled study-specific effects, future-trial prediction, and prior-sensitivity analysis. 🧰 WHAT YOU WILL RECEIVE • Publication-ready tables and figures • Reproducible scripts, syntax, and structured outputs • Clean, documented datasets where applicable • Reviewer-ready statistical summaries • Clear explanation of results, not just software output • Careful interpretation of assumptions, uncertainty, limitations, and robustness concerns • Milestone-based delivery for larger or unclear projects 🧠 STATISTICAL SOFTWARE & TOOLS • R • Mplus • Python • Stata • SPSS • AMOS and SmartPLS available when specifically required 💡 WORKING STYLE Upwork Verified: Detail-Oriented Work Style. I do not simply run models. I help ensure that the statistical approach fits the research question, the workflow is transparent and reproducible, the results are interpreted responsibly, and the conclusions are defensible. For larger, complex, or unclear projects, I often recommend starting with a focused review or small fixed-price milestone. This helps clarify the research question, dataset structure, model feasibility, key assumptions, deliverables, and reporting expectations before full analysis begins. If your project involves unclear model choices, reviewer comments, complex data, or results that need to be defensible, send me a brief overview of the research question and current statistical concern. I can help identify the safest first milestone and the most appropriate analytical path forward.
