This dataset contains two functional covariates and one scalar covariate. The goal is to predict the heat value of some fuel based on the ultraviolet radiation spectrum and infrared ray radiation and one scalar column called h2o.
This is a subset of the full dataset, which is contained in the package FDboost.
