I have a clinical research dataset that combines numerical outcomes, survey ratings, and a small set of open-ended responses. I need a full statistical workflow in R that begins with data cleaning and ends with publication-ready tables, figures, and a concise interpretation of results. The job covers descriptive summaries to profile the sample, hypothesis-driven inferential tests, and multivariate modelling to tease out relationships between key clinical variables and patient-reported outcomes. The qualitative portion is modest, so a brief content or sentiment extraction that can be quantified for integration into the models will be required. Because everything must align with CONSORT guidelines, please annotate each step in your R scripts so the methods section in the manuscript can be lifted directly from your code comments. Deliverables: • Annotated R scripts (well-commented, runnable on R 4.x) • Cleaned, fully documented dataset (CSV or RDS) • A short statistical report summarising methods, assumptions checked, and main findings, with APA-style tables and ggplot2 figures • A one-page addendum explaining how the qualitative insights were coded and merged with the quantitative set I will provide the raw data, study protocol, and specific clinical questions once we start. Turnaround within two weeks would be ideal, but let me know if you foresee a more efficient timeline.

Mixed-methods clinical datasets require a workflow that bridges statistical rigor with qualitative depth—most practitioners treat these as separate analyses when they should be integrated from the outset. This project sits at that intersection: cleaning and profiling the sample, running hypothesis-driven inferential tests, then building multivariate models that incorporate coded qualitative insights. Deliverables demand CONSORT-aligned R code with inline documentation sufficient for direct manuscript extraction. The statistical report needs APA tables, ggplot2 figures, and transparent assumptions checking. The qualitative portion—content/sentiment extraction from open-ended responses—must be quantified and merged back into the model set without losing interpretive nuance. Two-week turnaround is feasible. Work proceeds in parallel: data cleaning and descriptive summaries run concurrently with protocol review and clinical question refinement. Multivariate modeling depends on output from earlier stages but can begin once hypothesis-specific variables are locked. Qualitative coding follows similar timeline, allowing integration into final models by week 10-12, leaving buffer for report writing and revision. Provide raw data and study protocol on acceptance. Annotated scripts, cleaned dataset, statistical report with publication-ready tables/figures, and qualitative coding addendum delivered within your timeline.

Hi, I am a data analyst specializing in statistical modeling and clinical research with 8 years of rich experience in software development. I am familiar with R Programming, Statistics, Statistical Analysis, Statistical Modeling, Data Visualization, ggplot2, SPSS Statistics, Qualitative Research, Data Analysis, and R Markdown. I understand that you need a complete mixed-methods analysis workflow that combines quantitative and qualitative clinical data in R. I can build a fully annotated and reproducible R workflow covering data cleaning, descriptive and inferential statistics, multivariate modeling, qualitative coding, publication-ready tables and figures, and well-documented outputs that support manuscript preparation and CONSORT reporting. I'm an individual freelancer and can work on any time zone you want. Please contact me with the best time for you to have a quick chat. Looking forward to discussing more details. Thanks. Emile.

Mixed-methods medical data analysis demands tight integration between statistical rigor and qualitative coding—where misaligned pipelines compromise both CONSORT compliance and manuscript-ready output. This project requires end-to-end R workflow construction: data cleaning, descriptive profiling, hypothesis-driven inference, multivariate modelling, and sentiment extraction from open-ended responses. The challenge lies in maintaining full auditability for peer review while ensuring the qualitative component integrates seamlessly into the quantitative framework. Deliverables span annotated R scripts, cleaned datasets, APA-formatted statistical reports with ggplot2 visualizations, and a coding addendum explaining qualitative-quantitative integration. Six years of statistical analysis across clinical datasets, combined with proficiency in R, SPSS, and multivariate modelling, ensures reproducible methods documentation suitable for publication. Turnaround within two weeks is feasible given the project scope and specificity. Provide raw data, study protocol, and clinical hypotheses upon engagement. All scripts will include methods annotations extractable for manuscript drafting, with full Turnitin reports included as standard.

Mixed-methods medical data analysis requires seamless integration of quantitative rigor with qualitative insight—a workflow that demands both statistical precision and narrative sensitivity. This project sits at that intersection. The scope covers the full analytical pipeline: data cleaning and validation, descriptive profiling, hypothesis-driven inferential testing, multivariate modelling, and qualitative sentiment extraction. R scripting with full annotation ensures reproducibility and direct alignment with CONSORT guidelines. Publication-ready tables and ggplot2 visualizations will follow APA formatting standards. The two-week turnaround is achievable. Clinical datasets of moderate complexity benefit from systematic cleaning protocols, assumption checking (normality, homogeneity, multicollinearity), and transparent reporting of all tests conducted. Qualitative coding will be quantified and merged as weighted predictors or categorical covariates depending on study design. Deliverables include fully annotated R scripts (R 4.x compatible), cleaned dataset documentation, statistical report with methods traceable to code comments, and a codebook for qualitative integration. This ensures the manuscript methods section drafts itself from the workflow documentation.

Thank you for considering my proposal. I have gone through the requirements in detail and understand that you need a complete statistical analysis workflow in R, from data cleaning through inferential analysis and multivariate modeling, with publication-ready outputs and fully annotated scripts. As a Chartered Accountant (ICAI) with 7+ years of experience in data analysis, statistics, and research reporting, I can develop a structured, reproducible workflow using R 4.x. The project will include data cleaning, descriptive and inferential statistics, regression or other appropriate multivariate models, APA-style tables, ggplot2 visualizations, and a concise report explaining methods, assumptions, and key findings. I can also code the qualitative responses into measurable variables and integrate them with the quantitative analysis while documenting the methodology clearly. All scripts will be well-commented, easy to reproduce, and organized to support manuscript preparation and future updates. Payment & delivery assurance: ✅ No upfront payment ✅ Release payment after completion or milestone ✅ Timely delivery ✅ 100% commitment to project completion Profile: https://www.freelancer.com/u/caajoys?sb=t I’m ready to begin as soon as you share the dataset and study protocol, and I can deliver a high-quality, publication-ready analysis within your timeline. Best regards.

Hi, "CLINICAL DATA ANALYSIS IN R" — you need a clear statistical workflow that can support a research paper. I will build a clean R workflow covering data preparation, descriptive analysis, statistical tests, modelling, and publication-ready tables and figures. I’ll keep scripts well commented so each method step is easy to understand and reuse. The qualitative responses can be coded into measurable themes and connected with the numerical results, while checking assumptions before interpreting findings. Which clinical outcomes and main research questions should the models focus on first? Looking forward to working with you.
