I thank the authors for their thorough responses to the reviewers' comments. After the revised version of the manuscript is uploaded, I intend to return this manuscript to the reviewers to ascertain whether they feel that their concerns have been addressed.

The reviewers have indicated that the authors have done a good job of satisfying most of the comments. Two concerns remain:
1) There are numerous typographical errors, misspellings, and other issues. Sometimes entire words/phrases are missing (e.g., Page 8, line 8). This will need to be corrected before publication.
2) One of the reviewers raised questions about understanding of the statistical tests. In my own reading, Section 2.3 is quite short, and the authors refer to another paper for all of their details. Some further explanation in this paper is necessary so that readers do not have to study another paper just to understand this one.
