Regression context for the Partial Least Squares framework for 
    Extreme values. Estimations of the Shrinkage for Extreme Partial Least-Squares 
    (SEPaLS) estimators, an adaptation of the original Partial Least Squares 
    (PLS) method tailored to the extreme-value framework.
    The SEPaLS project is a joint work by Stephane Girard, Hadrien Lorenzo and 
    Julyan Arbel.
    R code to replicate the results of the paper is available at 
    <https://github.com/hlorenzo/SEPaLS_simus>.
    Extremes within PLS was already studied by one of the authors, see M 
    Bousebeta, G Enjolras, S Girard (2023) <doi:10.1016/j.jmva.2022.105101>.

Stratigraphic ranges of fossil marine animal genera from Sepkoski's
    (2002) published compendium. No changes have been made to any taxonomic 
    names. However, first and last appearance intervals have been updated to be
    consistent with stages of the International Geological Timescale. 
    Functionality for generating a plot of Sepkoski's evolutionary fauna is also
    included. For specific details on the compendium see:
