Freelance R Expert Needed: Advanced Signal Processing for Maternal, Fetal & Neonatal Health We are seeking a senior R scientist with deep experience in audio / seismic data, wavelet methods, and Bayesian modeling to help demonstrate that R is just as good as Python at surfacing early physiological health markers. This role is for someone comfortable working below the noise floor—where the signal of interest is subtle, nonstationary, and embedded in the mechanics of living systems. What you’ll work on 1. Signal conditioning & noise removal • Design and evaluate signal conditioning pipelines for low-amplitude physiological data • Implement filtering strategies to remove mains contamination (50/60 Hz and harmonics), including: o Notch / comb filters o Adaptive ...

I have a protocol ready for a medical meta-analysis that centres on knee replacement. The aim is to move from a well-defined research question to a manuscript that can be submitted to a peer-reviewed journal. Scope of work The review will synthesise existing literature on knee replacement, with the current plan calling for the inclusion of studies categorised under “Meta-analysis.” I will share my preliminary search strings; you can refine them and run comprehensive searches in PubMed, Embase, Cochrane Library, Web of Science and any other databases you judge relevant. All steps must align with PRISMA and the Cochrane Handbook. Statistical tasks Use RevMan, Stata or R (meta/metafor) to: • extract study-level data, • calculate pooled effect sizes (risk ratio,...

I need help transforming my existing systematic review into one that includes a meta-analysis. I already have an abstract prepared and a collection of articles with the necessary data. Requirements: - Conduct a meta-analysis using categorical data - Utilize odds ratio (OR) as the effect measure - No specific software preference (RevMan, R, or Stata) Ideal Skills & Experience: - Expertise in systematic reviews and meta-analyses - Proficiency in statistical software (RevMan, R, Stata) - Strong background in handling categorical data and calculating odds ratios I would appreciate this be done in 1-2 weeks times.

I have a complete, cleaned dataset ready to import into SPSS AMOS and need a full confirmatory factor analysis that illuminates the mechanisms behind South African women’s self-undermining behaviours and the complex route to their first promotion. The stated objective is “CFA analysis,” so the work should focus squarely on testing the proposed factor structure, reporting model fit, and demonstrating validity. Please run the model in SPSS AMOS (v26 or newer preferred) and return: • the .amw model file and raw output • fit statistics (χ²/df, CFI, TLI, RMSEA, SRMR) • standardised loadings, error variances, CR and AVE values • a brief write-up (2–3 pages) interpreting the findings and noting any modification indices that warrant disc...
