Analyses
Statios exposes 600 analysis handlers organised by namespace:
| Namespace | Examples |
|---|---|
stats.* | descriptives, frequencies, correlation, partial correlation, effect sizes |
test.* | t-test, ANOVA, chi-square, Kruskal-Wallis, Jonckheere, sign / runs tests... |
model.* | OLS, ridge, LASSO, elastic net, robust, quantile, IV-2SLS, ARDL, NLS, mixed models, panel FE/RE, ZIP/ZINB, MIDAS... |
survival.* | Kaplan-Meier, Cox, life table |
causal.* | DiD, RDD, RKD, PSM, IPW/DR, mediation, LATE, Lee bounds, bunching, event study |
ts.* | ADF, KPSS, ARIMA, GARCH/EGARCH/GJR/DCC, VAR, Granger, cointegration, MIDAS, TAR |
ml.* | Random Forest, XGBoost, SVM, decision trees, SHAP, train/test predict |
bayes.* | linear/logistic/hierarchical PyMC models, MCMC diagnostics, PPC, Bayes factors |
survey.* | design-based estimation, replicate weights, Rao-Scott |
analysis.* | PCA, EFA, hierarchical clustering, K-means, Cronbach, split-half, canonical |
meta.* | fixed/random effects meta-analysis, Egger's test, forest plot |
Each handler appears in:
- A dedicated form in the Analyze menu (with variable pickers and option tooltips), or
- The Command Palette (
Ctrl+K) for niche operations with a JSON params editor.
Variant selectors
Many forms group related variants behind a single dialog with a top-row selector — the same pattern as SPSS's tabbed dialogs. Examples:
- Regression form contains 13 model types (OLS / Ridge / LASSO / Elastic Net / Robust / Quantile / Stepwise / WLS / FGLS / IV-2SLS / ARDL / Truncated / NLS), with the right-side options swapping based on the chosen variant.
- ANOVA has One-Way / Two-Way / Repeated Measures.
- Missing Data has Simple / KNN / MICE / EM / PMM / Patterns / Sensitivity.
- Bootstrap has SE / CI / Regression / Jackknife / Permutation / Bayesian.
