Query: Cox's proportional hazards model with a high-dimensional and sparse
  regression parameter   This paper deals with the proportional hazards model proposed by D. R. Cox in
a high-dimensional and sparse setting for a regression parameter. To estimate
the regression parameter, the Dantzig selector is applied. The variable
selection consistency of the Dantzig selector for the model will be proved.
This property enables us to reduce the dimension of the parameter and to
construct asymptotically normal estimators for the regression parameter and the
cumulative baseline hazard function.
