Measurements from 39 Type Ia supernovas.
This is a regression dataset, with
magnitude the actual size of the supernova
E1-E10 the spectral energy in 10 different frequency bands.
These supernovas were close enough to to earth to actually observe their magnitudes. The idea is to build a model for predicting the magnitude based on the 10 energy measurements.
The data can be read with the command
supernova
<- read.table("http://hastie.su.domains/CASI_files/DATA/supernova.txt",
