Description
The Fall 2024 SDS Seminar Series continues on October 18th from 2:00 p.m. to 3:00 p.m. with Dr. Sherry Zhang (Postdoctoral Fellow, Department of Statistics and Data Sciences, University of Texas at Austin). This event is in-person in the Avaya Room (POB 2.302).
Title: Pivoting between Space and Time: Spatio-Temporal Analysis with Cubble
Abstract: Multivariate spatio-temporal data have a spatial component referring to the location of each observation, a temporal component recorded at regular or irregular time intervals, and multiple variables measured at each spatial and temporal value. Often, such data are fragmented, reflecting a common practice of focusing on either spatial or temporal aspects separately. This fragmentation makes it difficult to handle them coherently and comprehensively. This work introduces a new data structure to facilitate the study of different portions or combinations of spatio-temporal data for exploratory data analysis. The proposed structure, implemented in the R package, cubble, organizes spatial and temporal variables as two facets of a single data object, allowing them to be wrangled separately or combined while ensuring synchronization. Examples will be provided to visualize weather station data with cubble using glyph maps.
