Professional, publication-ready statistics — 150+ procedures verified against R, running entirely in your browser. Nothing to install, your data never leaves your device.
Nine specialized statistical suites — from core hypothesis testing to econometrics, biostatistics, SEM, and psychometrics.
Comprehensive statistical analysis: descriptive, hypothesis tests, ANOVA, correlation, regression, cluster analysis, time series, and more.
Advanced econometric models: ARIMA, VAR, GARCH, cointegration tests, panel data, Granger causality.
Specialized clinical tools: ROC curve, meta-analysis, Bland-Altman, epidemiological measures, clinical sample size, survival and dose-response.
Specialized spatial analysis: Moran's I, Geary's C, spatial autocorrelation, density maps, SAR/SEM models, geographically weighted regression.
Confirmatory factor analysis, structural equation modeling, path diagrams, fit indices (CFI, RMSEA, SRMR), modification indices, and indirect effects.
Comprehensive DOE module: CRD, RCBD, Latin Square, Factorial, Split-Plot, ANCOVA, Repeated Measures, Crossover, Nested, and Response Surface (RSM) — with post-hoc tests, APA tables, and R/lavaan verification.
Statistical process control: X̄-R, X̄-S, I-MR, p, c, u charts, CUSUM, EWMA, Run Charts — process capability (Cp, Cpk, Pp, Ppk, Cpm) and Measurement System Analysis (Gauge R&R, Bias & Linearity).
Advanced psychometric analysis: Item Response Theory (1PL/2PL/3PL Rasch), Differential Item Functioning (DIF), Latent Class Analysis (LCA), Equivalence Testing (TOST), and McDonald’s omega reliability — publication-ready output.
