Partial least squares (PLS) approach is proposed for linear discriminant analysis (LDA) when predictors are data of functional type (curves). Based on the equivalence between …
A new method for clustering functional data is proposed under the name Funclust. This method relies on the approximation of the notion of probability density for functional random …
With the emergence of numerical sensors in many aspects of everyday life, there is an increasing need in analyzing multivariate functional data. This work focuses on the …
Recently, an R package was developed for categorical functional data analysis (CFDA). This statistical approach extends the usual functional data analysis to temporal categorical data …
