Response to Reviewer

We sincerely thank Reviewer 1 for referring us to four relevant papers [1-4]. Paper [1] provides a very interesting relationship between Fisher divergence and Stein's operator, whereby Hyvarinen Paper [4] establishes a more general result than that of S. If the model class is well-specified then convergence to the data generating distribution is guaranteed. Fano's inequality also gives lower bounds of model selection/message decoding error (so larger'A kernelized Stein discrepancy for goodness-of-fit tests.' We appreciate Reviewer 2's comments and recommendations. We will do another proof reading and remove typos.
