Abstract: The FSDA (Flexible Statistics for Data Analysis) toolbox is a software library that extends MATLAB and its Statistics Toolbox to support a robust and efficient analysis of complex datasets, affected by different sources of heterogeneity. FSDA was born around the forward search approach, and has evolved into a comprehensive and computationally efficient software package for robust statistics. FSDA provides tools for regression and multivariate analysis, robust transformations, cluster analysis and model selection. FSDA provides a rich set of graphical features not available in R, such as dynamic brushing, linking, etc., particularly useful for exploratory data analysis. The only downside is that FSDA is based on commercial software (MATLAB), which is not so appealing to the majority of the statistical community, where R is more widespread. An R package (called fsdaR) compliant with R coding and calling standards (object-oriented approach, formula notation, etc.) is now available in CRAN. This package provides to R users selected features of the FSDA toolbox along with some of its advanced graphical capabilities. Among these features are regression and multivariate analysis with all the diagnostic and exploratory data analysis features available in FSDA. Our presentation will focus on i) The structure of the fsdaR package; ii) computational and graphical features of FSDA available in R through fsdaR, iii) A live demo.
