Parallelism, uniqueness, and large-sample asymptotics for the Dantzig selector
The Dantzig selector (Candès and Tao, 2007) is a popular ℓ(1)-regularization method for variable selection and estimation in linear regression. We present a very weak geometric condition on the observed predictors which is related to parallelism and, when satisfied, ensures the uniqueness of Dantzig...
