Joseph A.

I'm Joseph Arbizo, Master of Statistics (and a Registered Medical Technologist also), owner of Arbizo Statistics Consulting - a Biostatistician and Epidemiology Data Analyst with 10+ years of experience supporting clinical, public health, and academic research. I help clients go from study design and sample size planning to clean, analysis-ready data, then deliver defensible models (statistical, epidemiological, spatial, temporal), clear interpretation, and publication-ready reporting. What I can help you with: - Study design support (cross-sectional, cohort, case-control, clinical studies) - Sample size planning and analysis plan aligned with your objectives - Data cleaning, coding and documentation (analysis-ready datasets + codebook) - Biostatistical analysis: descriptive, bivariate, multivariate modeling - Epidemiologic methods: effect measures, confounding, interaction, model diagnostics - Survival analysis: Kaplan-Meier, log-rank, Cox regression - Spatial & time series analysis: mapping and spatial summaries, cluster/hotspot exploration, trends over time, time series/seasonality or pre-post comparisons, spatiotemporal visualization - Reporting: results tables/figures + clear interpretation for manuscripts and presentations Tools: R, SPSS, Stata, MS Excel, QGIS (and dashboards when needed) If you want a biostatistician who is responsive, careful with assumptions, and clear in communication, send your objectives and dataset, and I'll propose the best analysis approach.
