On the concept of depth for functional data
Web1 de jan. de 2024 · In this paper, we address the problem of getting order statistics for georeferenced functional data by means of depth functions. To reach this aim, we introduce the concept of spatial dispersion ... WebFinally, through this depth, we generalize to functions the Wilcoxon rank sum test. It allows testing whether two groups of curves come from the same population. This functional rank test when applied to children growth curves shows different growth patterns for boys and girls. KEY WORDS: Data depth; Functional data; Rank test for functions. 1.

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 … WebI am an electronics engineer having 2+ years of experience and in depth knowledge of electric vehicles, batteries and battery management systems including hands-on experience of working on the BMS of different topologies with cross functional background as a former field application engineer and current work on …
