Eikos: Statistics & Data

Eikos is a comprehensive statistical computing, data science, and research platform engineered for iOS, iPadOS, and macOS. It functions 100% offline and maintains your datasets under your exclusive sovereignty. Unlike simplistic calculators or static summaries, Eikos features a proprietary mathematical engine rigorously validated across 50,000+ test assertions against R Core and Python (SciPy/Statsmodels). VERIFIED STATISTICAL ENGINE • High-precision numerical computing matching standard scientific benchmarks. • 51 complete statistical procedures: descriptive statistics, hypothesis testing (Student's t, ANOVA, Mann-Whitney, Wilcoxon, Chi-Square, Fisher's exact). • Biostatistics & Survival Analysis: Kaplan-Meier estimation, Cox Proportional Hazards, Aalen-Johansen multi-state transitions, and Gray's competing risks. • Econometrics & Time Series: ARIMA modeling, GARCH(1,1) volatility, and hierarchical reconciliation. • Causal Inference & Epidemiology: Instrumental Variables (2SLS, Anderson-Rubin), Difference-in-Differences (DiD), Synthetic Control, and Causal Forests. NATIVE IMPORT & REPRODUCIBLE CODE • Direct parsing and analysis of native data formats: CSV, TSV, Microsoft Excel (.xlsx), R (.rds), Stata (.dta), SPSS (.sav), and structured JSON. • Instant generation of reproducible R and Python scripts for every analysis conducted. • Publication-ready report exports: APA / Vancouver / Table 1 formatting with LaTeX mathematical typesetting. INTEGRATED IDE & LEARNING ENVIRONMENT • 537 comprehensive guides organized across 8 disciplines. • Interactive Notebook with complete analysis history and methodology tracking. • Command console and local SQL engine for fast querying and table manipulation. • Formative challenge bank with adaptive scoring powered by Item Response Theory (IRT). Designed for researchers, biostatisticians, epidemiologists, university faculty, and students who require uncompromised mathematical accuracy and data privacy.
