Confidence Sets Based on Sparse Estimators Are Necessarily Large

Author

  • Pötscher, Benedikt M.

Abstract

Confidence sets based on sparse estimators are shown to be large compared to more standard confidence sets, demonstrating that sparsity of an estimator comes at a substantial price in terms of the quality of the estimator. The results are set in a general parametric or semiparametric framework.
