One-way ANOVA.
- Tests: F, T, Levene, U-Mannwhitney.
- Regression: Simple, Multiple (OLS), Probit and Logit
- Factorial Analysis: Extraction (PCA and Principal Axis), Rotation (Varimax,
Equimax, Quartimax) and Parallel Analysis and Velicer's MAP test, for
estimation of number of factors.
- Reliability analysis for simple scale and a DSL to easily analyze multiple
scales using factor analysis and correlations, if you want it.
- Dominance Analysis, with multivariate dependent and bootstrap (Azen &amp; Budescu)
- Sample calculation related formulas
- Structural Equation Modeling (SEM), using R libraries +sem+ and +OpenMx+
- Creates reports on text, html and rtf, using ReportBuilder gem
