%description
Provide functions to estimate the coefficients in high-dimensional linear
regressions via a tuning-free and robust approach. The method was
published in Wang, L., Peng, B., Bradic, J., Li, R. and Wu, Y. (2020), "A
Tuning-free Robust and Efficient Approach to High-dimensional Regression",
Journal of the American Statistical Association, 115:532, 1700-1714(JASA’s
discussion paper), <doi:10.1080/01621459.2020.1840989>. See also Wang, L.,
