We thank all the reviewers for their efforts and constructive comments, which help improve the quality of our paper. Based on the analysis of the first and second moment of the estimator presented in Theorems 5.1 and 5.2, a Chebyshev's type error bound can be easily [obtained:] We will present it as a corollary in the final version. We will add this discussion to the final version. Better figure representing MSE vs p. Thanks for the suggestion and we will revise our paper accordingly. It shows that RMSE decreases as p increases.
