## What is Eikos?

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.

• Updated AI model catalog.

### 1.0.18 — 2026-10-03

Eikos 1.0.18
