I want to quantify how recent advances in artificial intelligence are influencing forecasts of French GDP. I already have access to long-run historical GDP time-series and would like you to work only with that dataset for now. The task is strictly quantitative: build and compare solid économétriques models that incorporate an IA variable (or proxy) and measure its marginal effect on growth projections. You will be free to choose among standard time-series techniques—VAR, ARDL, error-correction, whatever proves statistically sound—provided the approach is fully documented and reproducible in R, Python, or Stata. Along the way, please explain every transformation, stationarity check, and specification test so that the methodology can be defended in an academic sett...

I want an Android app that SIMULATES crash game behavior for PROBABILITY ANALYSIS purposes. Requirements: - Simulated crash rounds based on probability models - Streak & volatility analysis - Auto-generated signals (Low / Medium / Avoid) - Target outcome accuracy around 75%

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 an IRB-approved protocol and SAP psychometric study of a digital cognitive wellness battery Scope of Work (must be included in proposal) Data QC and cleaning Validate export integrity, missingness review, recodes per data dictionary Produce analysis-ready dataset + QC notes (queries list) Primary reliability analysis ICC(3,1) with 95% CI Run two ICC approaches for verification (ANOVA-derived ICC and psych::ICC output) and confirm they match as expected Secondary analyses Domain/task ICCs with CIs Practice effects (paired tests + effect sizes) Usability (SUS/TAM) summary Completion rates, validity flags, session duration Exploratory correlations with SLUMS Deliverables Reproducible R repo (scripts, README, session info, locked outputs) Word-ready statistical report (tables + concise...

At I am expanding an internal project that explores fresh ideas in machine learning and need an intern who can jump straight into the research cycle—formulating hypotheses, building quick prototypes, running experiments, and summarising insights for the team. What you will do • Survey recent ML literature that aligns with our roadmap • Design and execute experiments to test new model architectures or training tricks • Record results, visualise them clearly, and explain the “why” behind the numbers • Iterate on your findings until we have a result worth integrating into production-grade code What you should bring Your application only needs to highlight relevant experience, but that experience must show strong analytical and problem-solving...

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...
