.huber_efficiency_const

Get the constant for the desired efficiency of the M-estimate of location
using the Huber \(\rho\) function

internal

Robust penalized (adaptive) elastic net S and M estimators for
linear regression. The adaptive methods are proposed in
Kepplinger, D. (2023) <doi:10.1016/j.csda.2023.107730> and the
non-adaptive methods in
Cohen Freue, G. V., Kepplinger, D., Salibián-Barrera, M., and Smucler, E.
(2019) <doi:10.1214/19-AOAS1269>.
The package implements robust hyper-parameter selection with robust
information sharing cross-validation according to Kepplinger & Wei (2025)
<doi:10.1080/00401706.2025.2540970>.
