I can realize univariate statistics (descriptive statistics, two paired tests, Anova) and applicate some multivariate techniques (principal components analysis, factor analysis, multidimensional scaling, etc.). Both parametric and non parametric analysis. Unlike others statistics packages, every graph in R is customizable. You can make useful and fun graphs with R.
Why choosing this gig? 5$ for a complete analysis, two free revisions and without any charge for the source code. However, colour-complex graphics could have an extra cost.
Things I can do: one sample and two sample hypothesis testing, descriptive statistics, simple linear regression, multiple linear regression, logistic regression, Anova, non parametric aproachs to Anova (Kruskal-Wallis, Friedman), parametric and no parametric post hoc analysis, etc.
Things I don't do (for now): forecasting and temporal series analysis, data mining, non-parametric multivariate aproachs (except NMDS), Bayesian inference.
I can also speak Spanish (write in Spanish if you wish).
