Web2logp in the Dantzig selector leads to relatively large bias in estimating the sparse regression co-efficient vector β. To reduce the bias, the authors suggest a two-stage pro-cedure called the Gauss–Dantzig selector which uses the original Dantzig selector for variable selection and then runs ordinary least squares on the selected variables.
