Multivariate regression data set from: https://link.springer.com/article/10.1007%2Fs10994-016-5546-z : The Solar Flare dataset (Lichman 2013) has 3 target variables that correspond to the number of times 3 types of solar flare (common, moderate, severe) are observed within 24 h. There are two versions of this dataset. SF1 contains data from year 1969 and SF2 from year 1978.
