5. Review Comments to the Author

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: The authors have done a concrete representation of their work with clear explanation on their method with simulation results. The authors may consider comparing their method to more comparators, but the display they have looks OK. The English in the manuscript is mostly straightforward with some minor revisions needed in some sentences. The detailed comments are provided in the attached pdf file.

Reviewer #2: Here are some suggestions I’d like to provide on your revisions:

1. Please elaborate on the literature review in the introduction part. It’s crucial to see what previous research works have been done in this area with their cons and pros. It is also important to highlight the research gap your research addresses and to clarify the motivation behind your research. This will provide readers with a more solid understanding of novelty and importance of your research.

2. In the section discussing simulation study, I saw you compared with two other existing methods. It might be helpful to provide a more detailed description on them, such as the one developed by Benjamini and Hochberg. Explain why you want to perform comparisons with those two methods, how your chosen methods differ and what advantages/disadvantages they might have.

3. On Line 111, you reference an 'eta' in equation (2), but it does not appear to be present. Please either introduce 'eta' in the equation or revise the text to reflect the equation correctly.

4. Make sure to be consistent in notations throughout the manuscript. Specifically, the use of subscripts such as 'i' and 'j' in your method.

5. On Line 267, the 'Z' is mentioned. Please provide a clear explanation of 'Z' so that readers can understand its meaning.

**********

6. PLOS authors have the option to publish the peer review history of their article (what does this mean?). If published, this will include your full peer review and any attached files.

If you choose “no”, your identity will remain anonymous but your review may still be made public.

Do you want your identity to be public for this peer review? For information about this choice, including consent withdrawal, please see our Privacy Policy.

selection method with FDR control for omics-wide association analysis.

I appreciate the efforts put in by the authors for revising the manuscript based on the

reviewer’s comments. The contents are much clearer, and the mathematical expressions

are easier to follow.

Upon reading the paper line by line, I have only had some minor comments. These are not

necessarily crucial in following the writing, but still stand out and could be disturbing for

future readers to some extent. Please find the line-by-line comments in the attached pdf file. In particular,

the comment regarding Line 133 should be addressed.

6. Review Comments to the Author

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: Thank you for the opportunity to read and review your work. I carefully read the revised manuscript and I do not have any further comments.

Reviewer #3: 

1. Introduction part: the authors utilize rank-based approach and SDA approach to develop a robust feature selection method for a single index model (SIM). Meanwhile, the authors introduce several methods of FDR controlled feature selection: Knockoff filter-based approach, Symmetrized data aggregation (SDA) approach, Stability selection approach. Based on these conceptions, can authors provide rationelle for integrate rank/SDA methods into SIM in the introduction part?

2. Results part: as observed from results, SIM-FDR is not always ranked to be highest in both aspects of FDR as well as Power. Can authors use a kind of overall/balanced evaluation method to judge that SIM-FDR is best when compared to other methods?

3. Results part: since massive human genomic data sets makes the dimensionality of omics features much larger than its sample size, can authors

also use real human genomic data sets to test performance of SIM-FDR?

4. Discussion: list ponits as above

Revision 4

Response to the comments of reviewer

Thank you very much for your helpful and constructive comments on our manuscript. We have amended our manuscript following your valuable suggestions. Specific replies to your comments are given below:

Reviewer #1: Thank you for the opportunity to read and review your work. I carefully read the revised manuscript and I do not have any further comments.

Reviewer #3:

1. Introduction part: the authors utilize rank-based approach and SDA approach to develop a robust feature selection method for a single index model (SIM). Meanwhile, the authors introduce several methods of FDR controlled feature selection: Knockoff filter-based approach, Symmetrized data aggregation (SDA) approach, Stability selection approach. Based on these conceptions, can authors provide rationelle for integrate rank/SDA methods into SIM in the introduction part?

Response: Thanks very much! We have provided some discussions in the revised manuscript in red between the lines 94 and 119.

2. Results part: as observed from results, SIM-FDR is not always ranked to be highest in both aspects of FDR as well as Power. Can authors use a kind of overall/balanced evaluation method to judge that SIM-FDR is best when compared to other methods?

Response: Thanks very much!

1. We first introduced the new measurement: Matthews correlation coefficient (MCC) to evaluate the performance of feature selection. MCC measures the overall accuracy of selection for true positives (TP), false negatives (FN), true negatives (TN), and false positives (FP), with a larger value indicating overall better selection (Baldi et al. 2000; Chicco and Jurman 2020). We have added some descriptions about MCC between the lines 476 and 479 in the revised manuscript in red.

2. The simulation results evaluated via the Matthews correlation coefficient (MCC) are shown in the revised manuscript in red between the lines 560 and 576.

3. Results part: since massive human genomic data sets makes the dimensionality of omics features much larger than its sample size, can authors also use real human genomic data sets to test performance of SIM-FDR?

Response: Thanks very much! We utilized the real Head and neck squamous cell carcinoma (HNSCC) data to further evaluate the performance of the proposed method. The Cancer Genome Atlas profiled 279 head and neck squamous cell carcinomas (HNSCC) to provide a comprehensive landscape of somatic genomic alterations. We have added the analysis of HNSCC data into the revised manuscript in red.between the lines 641 and 693.

4. Discussion: list ponits as above

Response: Thanks very much! We have reconstructed the “Discussion” section in the revised manuscript in red between the lines 694 and 737.
