Package: wnpp
Severity: wishlist
* Package name : ruby-statsample
Version : 1.4.3
Upstream Author : Claudio Bustos

standard error, skew, kurtosis (and many others).
- Imports and exports datasets from and to Excel, CSV and plain text files.
- Correlations: Pearson's r, Spearman's rank correlation (rho), point
biserial,
tau a, tau b and gamma. Tetrachoric and Polychoric correlation provides by
statsample-bivariate-extension gem.
- Intra-class correlation
- Anova: generic and vector-based One-way ANOVA and Two-way ANOVA, with
contrasts for
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 &
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
- Graphics: Histogram, Boxplot and Scatterplot.

This package is a dependency of ruby-statsample-timeseries. I have
started packagig at
https://anonscm.debian.org/cgit/pkg-ruby-extras/ruby-statsample.git/ ,
but I don't have time to finish it in the near future, hence the RFP.
Cheers,
Balint
