L1 penalized LAD estimator for high dimensional linear
... This choice of penalty replies on moment conditions of X and relative size of p and n, but it could be smaller than the previous ones and in practice it will cause less bias. We investigate the effect of different penalties in the numerical study section. To simplify our arguments, in the following ...
