Axis 3: Categorical functional data analysis

Participants : Cristian Preda, Quentin Grimonprez, Vincent Vandewalle.

The research on functional data analysis is very actual. The R package "fda" is the most famous one implementing methodology for functional data. To the best of our knowledge, and quite surprisingly, there is no recent researches devoted to categorical functional data despite its ability to model real situations in different fields of applications: health and medicine (status of a patient over time), economy (status of the market), sociology (evolution of social status), and so on. We have developed the methodology to visualize, do dimension reduction and extract feature from categorical functional data. For this, the cfda R package has been developed.
