Karel Hron, Czech Science Foundation project 25-15447S, submitted March 2024 "Distributional data analysis for geochemical mapping" The aim is to use general theory of density data analysis using Bayes spaces for functional exploratory data analysis in geochemical context. Abstract: The project will bridge the gap between realms of geosciences and statistics and build new methodological foundations for processing large-scale multidimensional geochemical data from soil monitoring, properly considering natural variability of these data as distributional data. The gap exists because geosciences and statistics have different foundations and i) a lack of intersection of research topics and ii) poor understanding among researchers due to terminological and knowledge incompatibilities.
