On the concept of depth for functional data
Web1 de jan. de 2011 · The notions of depth for functional data provide a way of ordering curves from center-outward. These methods are designed for trajectories that are observed on a fine grid of equally spaced time points. However, in many applications the trajectories are observed on sparse irregularly spaced time points. We propose a model-based … WebRecently, functional data analysis [] was extended to the study of geostatistical functional datasets [].In this context, each curve is a sample of a continuous spatial functional process so that the dataset to analyze is made by units which include a spatial component (usually in \(\mathfrak{R}^{2}\)) and a functional component.. The interest in the analysis of …
