Analysis of multiple waveforms by means of functional principal component analysis: normal versus pathological patterns in sit-to-stand movement
Springer Verlag (2008)This paper presents an application of Functional Principal Component Analysis (FPCA) to describe inter-subject variability of multiple waveforms. This technique was applied to the study of sit-to-stand movement in two ... -
Geofd: An R Package for Function-Valued Geostatistical Prediction
Universidad Nacional de Colombia (2015-12)Spatially correlated curves are present in a wide range of applied disciplines. In this paper we describe the R package geofd which implements ordinary kriging prediction for this type of data. Initially the curves ... -
Multivariate functional random fields: prediction and optimal sampling
Springer Verlag (2017)This paper develops spatial prediction of a functional variable at unsampled sites, using functional covariates, that is, we present a functional cokriging method. We show that through the representation of each function ... -
Ordinal classification of 3D brain structures by functional data analysis
Elsevier B.V. All (2021-08-24)We introduce several ordinal classification methods for functional data, specificallymultiargument and multivariate functional data. Their performance is analyzed in fourreal data sets that belong to a neuroeducational ...
