FSDA Matlab code

FSDA logoFSDA Toolbox extends MATLAB and statistics toolbox to support a robust and efficient analysis of complex data sets.
FSDA was first released on March 2012.
Last update: June 16, 2015


You can have a look at the toolbox features through a short video or through some didactic movies
Movie 1:Hawkins data
Movie 2:Fishery data
Movie 3:AR data
Movie 4:Loyalty cards data
Movie 5:Hospital data

Installation notes

In the Installation Note pdf file we tried to document all that you have to expect when FSDA is installed manually by unpacking the compressed tar file FSDA.tar.gz, or automatically with our setup program for Windows platforms.

Download FSDA A setup executable for MS Windows platforms will install the toolbox and update the search path of your local MATLAB installation.

Download a compressed tar file of the toolbox, suitable for Unix platforms installation. In this case, you have to add manually FSDA folder and sub-folders to the MATLAB path or use our routine addFSDA2path.

Download a working paper describing the main characteristics of the FSDA toolbox or see Riani, Perrotta, Torti (2012).

Highlights of the last releases

______________________________________________________ June 2016 Release (v.3.2)

Major statistical release. Highlights:

  • New features added to the tclust function, including determinant restriction and new adjusted BIC criterion for the estimation of the number of groups.
  • Added functions for reweighting FSR and FSRB (FSRr and FSRBr).
  • Functions FSR, FSRB and FSRH redesigned; a routing implementing the core of the Forward Search algorithm (FSRcore) introduced to avoid code redundancies.
  • New function, winsor, to winsor data.
  • New function FSMbsb, which will replace FSMbbm.
  • New function randindexFS, to evaluate the quality of different clusterings.
  • New routines poolClose and poolPrepare introduced to conveniently open and close a pool of parallel workers.
  • Several new robust functions to generate, for example, the Tukey Biweigh rho function (HUrho), the tuning constant associated to a certain efficiency (HUeff), the psi functions (HUpsi), its derivative (HUpsider), etc. For a full list, see functions under utilities_stats folder.

Major highlights in the documentations and examples:

  • New function, publishFS, introduced to generate documentation pages directly from the .m files.
  • New function, makecontentsfileFS, introduced to create a the list of files present in a FSDA folder and/or subfolders. It extends MATLAB function makecontentfilesFS.
  • .mlx files introduced for examples_multivariate and examples_regression
