I provide a wide range of data science support, centered on medical and healthcare research — from statistical analysis, data preparation, and the creation of figures and tables for papers and conference presentations, to results reports and statistical advice.

A. I propose and apply the method best suited to your research objectives, including: descriptive statistics (mean, standard deviation, median, and so on); various tests (t-tests, chi-squared tests, the Mann–Whitney U test, the Wilcoxon signed-rank test, the Kruskal–Wallis test, Fisher's exact test, multiple comparison procedures, and so on); correlation analysis (Pearson, Spearman); regression analysis (simple regression, multiple regression, logistic regression, Cox proportional hazards models, generalized linear models, generalized estimating equations (GEE), mixed-effects models); survival analysis (Kaplan–Meier curves, the log-rank test); multivariate analysis (principal component analysis, factor analysis, cluster analysis, discriminant analysis); propensity score analysis (matching, IPTW); ROC curve analysis; diagnostic accuracy studies; and sample size determination.

The Figure Plan specializes in creating high-quality figures and tables for papers and presentations, mainly from data that has already been analyzed. The Analysis Plan is for those who want to entrust the full sequence of statistical work to a specialist — from data preparation through analysis, interpretation of results, and report writing.

They can be used as services added to the basic plans (Figure / Analysis), or to commission a specific task on its own (for example, data preparation only, or a particular piece of statistical advice only). I respond flexibly to your specific needs.

First, please contact me through the inquiry form on the website, including the details of what you would like to discuss. If the form is difficult to use, I also accept direct email.

Yes — consultations and the initial hearing are free of charge. Even if our discussion does not lead to a contract, no fee will be charged, so please rest assured. And even once a contract is concluded, I do not begin work until payment is confirmed; signing a contract therefore does not in itself commit you to a payment, so please feel free to raise any questions. Start by telling me about your situation in detail.

Communication is generally by email.

Once you agree to the proposed approach and the estimate, we conclude the basic service agreement by electronic signature using GMO Sign. There is no need for you to create a new GMO Sign account.

Yes — you can review the contract terms in advance on the "Sample Service Agreement" page of the website.

After a consultation about the details of your request (the complexity of the analysis, the volume of data, the deliverables required, and so on), I provide an individual estimate.

Payment is by credit card only, processed securely through Stripe. You can pay with an overseas-issued card directly via a secure payment link I email to you — there is no need to exchange bank details or arrange an international wire. Major cards (Visa, Mastercard, American Express, etc.) are accepted.

A. After the contract is concluded, I ask that payment be made before work begins.

Your data is strictly subject to confidentiality under the basic service agreement. Dr.DataScience is a sole proprietorship, and because I (Kenichiro Suzuki) perform all analysis personally, nothing is ever outsourced — keeping the risk of information leakage to a minimum.

Yes — the basic service agreement includes provisions on confidentiality. If you require a separate, standalone NDA, please let me know.

Results are provided as a clearly organized "results table" and a "results report" that includes detailed explanation. I also create and deliver high-quality figures and tables ready to use directly in papers and presentations.

Yes, I can provide the program code used in the analysis; however, because such code constitutes intellectual property, it is provided for an additional fee. Please discuss the details when we prepare your estimate.

Yes — a major strength of Dr.DataScience is that, even after the contract is complete, I answer questions about the analysis carefully and free of charge, with no time limit. I support you so that you can devote yourself to your research with peace of mind over the long term.

Yes, I can. As needed, I help prepare responses to reviewers' statistical questions. This is part of the support I offer to raise the quality of your paper.

Dr.DataScience has handled many commissions from public medical institutions and university-affiliated research institutes, and has also earned high ratings on CrowdWorks. Owing to contractual restrictions, I cannot disclose the names of individual research institutions or the details of specific projects, but I bring abundant experience and a track record of helping clients solve their challenges.

No — in principle, there is no need to credit me in your paper. However, if you wish, you are welcome to include the name Dr.DataScience (Kenichiro Suzuki) in the acknowledgments or similar.

Yes. From your first inquiry and consultation through analysis, delivery, and after-care support, I work entirely in English. Results tables, reports, figure labels and captions, and code comments can all be prepared in English, ready for submission to English-language journals.

Yes. Dr.DataScience is a sole proprietorship, and I (Suzuki) handle every project personally from start to finish. Nothing is ever outsourced, so international clients receive consistent quality and confidentiality throughout.

I am based in Japan (UTC+9). Because most communication is by email, the time difference rarely causes any issue — I usually reply within 24 hours. Delivery timelines are agreed in advance based on the scope of your request.

I observe Japanese public holidays. If any of them might affect your schedule, I will let you know in advance.

A. Charges are denominated in US dollar (USD). When you pay with an overseas card, the amount is automatically converted into your own currency at your card issuer's exchange rate (the figure on your statement may vary slightly depending on that rate and any card-issuer fees).

I cover the card-processing fee, so no separate surcharge is added to your invoice. Please note, however, that any currency-conversion or foreign-transaction fees charged by your own card issuer may still apply.

Yes. I issue a formal invoice stating the services, amount, date, and my business details. Please tell me any specific fields your institution requires. Note that the Japanese "qualified invoice" registration number is for Japan's consumption-tax system and is generally not relevant to overseas reimbursement.

(Draft) Services provided to non-residents outside Japan and used abroad are generally exempt from Japanese consumption tax (export exemption), so overseas clients can often be invoiced at the tax-exclusive amount. Because tax treatment depends on individual circumstances, please confirm the details with a tax professional.

(Draft) As a non-US foreign sole proprietor, I can complete a W-8BEN (for foreign individuals) if your US institution requests one. Please let me know what documentation you need.

I agree on a secure method in advance (encrypted file transfer, password-protected archives, or a secure cloud link that you control). Wherever possible, I recommend providing de-identified data.

The master agreement is governed by Japanese law, with jurisdiction in Tokyo, Japan. This is standard for a Japan-based provider. You can review the full contract before signing.

An English reference translation of the agreement is available. Please note that the legally binding original is the Japanese version, which prevails in the event of any discrepancy.

I conclude the contract by electronic signature using GMO Sign. You do not need to create an account; you simply sign via a link I email to you. This works without any problem from overseas.

I primarily use R, Python (and other software as needed). I deliver outputs and figures in formats convenient for you. The program code used for analysis and figures is available for an additional fee, as it constitutes intellectual property.

Yes. I can present and report results in line with reporting guidelines such as STROBE and CONSORT, and follow the conventions of your target journal (e.g., AMA or APA style, ICMJE).

Yes. I have supported the statistics sections, results presentation, and reviewer-response preparation for submissions to English-language journals.
