a new sub-chapter on Variable Selection by using least absolute shrinkage and
selection operator (LASSO) and its general form the so-called Elastic Net.
All pictures and numerical examples have been now calculated in the (almost)
standard language R & MATLAB. The code for each picture is indicated with
asmall sign near the picture, e.g. MVAdenbank denotes the corresponding
quantlet for reproduction of Fig.1.9, where we display the densities of the diagonal
of genuine and counterfeit bank notes. We believe that these publicly available
quantlets (see also http://sfb649.wiwi.hu-berlin.de/quantnet/) create a valuable
contribution to distribution of knowledge in the statistical science. The symbols and
notations have also been standardised. In the preparation of the fourth edition, we
received valuable input from Dedy Dwi Prastyo, Petra Burdejova, Sergey Nasekin
and Awdesch Melzer. We would like to thank them.
