The Brazilian Journal of Biometrics is an international scientific journal that publishes original research papers, discussion papers, points of view, reviews and short notes.

Submissions should be done electronically using the OJS Web interface https://biometria.ufla.br/index.php/BBJ/login

 The Brazilian Journal of Biometrics publishes papers strongly connected with statistical, mathematical and data science methodology, with application to biological sciences.



Starting in January 2021, the Brazilian Journal of Biometrics only published papers written in English. In this transitional phase, authors still have the chance of submitting their papers in Portuguese (strongly discouraged) however, if their paper is conditionally accepted based on the scientific contents, it will undergo a second round with scientific and language reviewers after the authors provide the English version of the conditionally accepted paper. A final acceptance for papers originally submitted in Portuguese can only be considered after positive review reports in both phases. For submissions in English, a standard review process with a single phase will be conducted.

We strongly recommend the authors to use the templates provided, either the .docx or the .tex. No paper will be accepted in another template.
Here you should write your introduction, including the literature review. In these guidelines we present an example for the structure of a research paper. However, the names of these sections can be changed by the authors.

The specifications for the forma of papers submitted to the Brazilian Journal of Biometrics are

The templates (.docx or .tex). To download click in Templates English.



The paper must be no longer than 20 pages and be structured in the following sections: title, author(s), abstract, keywords, introduction, matherials and methods, results and discussion, acknowledgements, and references. The manuscripts should include page number.

Title: It should be concise and informative and avoid abbreviations, acronyms and formulae where possible.

Author(s): It should be written in full and only the last name in capitals. Scientific affiliation of author(s) should be indicated in a footnote (University, Department, Postal Code, City, State, Country, E-mail Address). Please inform the ORCID number of all authors.

Abstract: It should indicate the content of the paper, and should provide the main conclusions. It should not exceed 200 words. References should be avoided.

Keywords: The authors must provide a maximum of seven keywords, separated by semicolons, which appropriately represent the contents of the paper. They should not repeat words that are already in the title.

Introduction: It should contain a critical assessment of the literature relevant to the problem at hand. It must state clearly the objectives of the study. This section may not be subdivided.

Development: Immediately following the introduction (numbered 1) develop your article by dividing it into clearly defined and numbered sections. Subsections should be numbered 1.1 (then 1.1.1, 1.1.2, ...), 1.2, etc. You must use this numbering for internal cross-referencing: do not just refer to 'the text'. Any subsection may be given a brief heading. Each heading should appear on its own separate line.

Acknowledgements: List here those individuals (if any) who provided help during the research (e.g., sponsors, technical assistance or proof reading the article, etc.).

References: The journal adopts the ISO 690:2010 formatting style for references. All references to other papers, books, etc., must be given at the end of the paper. They should be numbered but should be listed in alphabetical order of the first authors´ surname. Citation of papers published in congress, conferences and similar proceedings should be avoided. Examples of references for a book, book chapter, paper in a journal, thesis and, a report on the web  are presented bellow:

All references must be cited in the text using the command  \citep{}  for inline references such as (Pereira et al., 2021), and using the command \citet{} for text references such as Zhang & Yi (2022) or Pereira et al. (2021). When citing two or more references in the text you can use (Deng et al., 2021; Huang, 2021). We strongly suggest that the authors to use the latex template and to include their references in a bibtex file. Please be sure that you run the BibTeX to be sure that the references are properly compiled.

If the authors do not use the bibtex file, they should include the references in the end of the document with the same style as in the examples. All references should be listed in alphabetical order of the first authors’ surname.
Examples of citations for books are: Bolle
et al. (2013) and Jain et al. (2007).

You must remember to be very careful about online sources. As you know, it is possible to put something on the internet in a personal right, so it is best to stick to academic or reputable sources for all your assignments.

Citation in text:

(a) You must ensure that every reference cited in the text is also present in the reference list (and vice versa).
(b) Unpublished results and personal communications are not recommended in the reference list, but may be mentioned in the text. If these references are included in the reference list they should follow the standard reference style of the journal and should include a substitution of the publication date with either 'Unpublished results' or 'Personal communication'. Citation of a reference as 'in press' implies that the item has been accepted for publication.
(c) In the text, authors´ surnames only should be given, followed by the year of publication (for three or more authors, only the first surname should be given, followed by italic: et al.; the abbreviations ibid., op. cit. and loc. Cit. are not used).
(d) Citations can be direct (textual transcription of the consulted work) or indirect (information based on the work consulted). In direct citations, the transcribed text must be distinguished (in italics or with quotation marks), followed by the citation, which must be in parentheses containing the author's surname in separated by a comma from the publication date. Ex.: “In many environmental examples where spatial correlation is considered, Euclidean distance is the natural metric that is used.” (Haggarty et al., 2015). In indirect citations, the text may precede or follow the citation, which should include the author's surname followed by the publication date. Ex.: It is widely know that misclassification can lead to severe bias as well as reduced statistical efficiency (Barron, 1977). Ex.: Witten and Tibshirani (2010) proposed an approach to sparse clustering for multivariate data.
(e) Whenever page specification is necessary, it must follow the date separated by a comma and preceded by p. Ex.: Mumford (1949, p. 513).
(f) Later citations of various works must be separated by semicolon (preserving the chronological order). Ex.: (Reiss, 1974; Box, 1974a; Box, 1974b; Breslow et al., 2010).
(g) Starting with citation of various works, they must be separated by comma. Ex.: Breslow (1974), Ferraty and Vieu (2006) and Reiss et al. (2010).


Notes: They must be reduced to a minimum number and placed in a footnote. Remission to the footnote must be accomplished by means of special superscript characters.

Tables: They must be consecutively numbered by Arabic numbers and headed by a title. The title must be preceded by the word Table. Place any table notes below the table body. Please submit tables as editable text and not as images. Tables should be placed next to the relevant text in the article. Be sparing in the use of tables and ensure that the data presented in them do not duplicate results described elsewhere in the article. The caption of the tables should be given above. The caption should be detailed enough for the table to be understood. Table titles should not be punctuated at the end of the text
Figures: They must be consecutively numbered by Arabic numbers. The title must be preceded by the word Figure and placed bellow the figure. Please submit figures as images with a good resolution. Tables should be placed next to the relevant text in the article, Be sparing in the use of tables and ensure that the data presented in them do not duplicate results described elsewhere in the article. Figures and their legends must be clearly readable. The caption of the figures should be given below the figures. The caption should be detailed enough for the figure to be understood.

Equations: Equation numbering, whenever necessary, must be sequential and in Arabic numbers aligned on the right. Its components must be in italics, except for numbers and functions.

Measurement units and symbols: These elements must be restricted to those conventionally used or sanctioned by usage. SI units should be used throughout. Unusual units must be clearly defined in the text.

Appendices: They should be identified as A, B, etc. Formulae and equations in appendices should be given separate numbering: Eq. (A.1), Eq. (A.2), etc.; in a subsequent appendix, Eq. (B.1) and so on. Similarly for tables and figures: Table A.1; Fig. A.1, etc.

To guarantee an anonymous peer review process for articles, do not insert author names in the manuscript file. Please remove any authorship identification from the files before submission.

Authors are fully responsible for data and concepts provided in the text as well as for the accuracy of references. Manuscripts that are non-compliant with these guidelines will be returned to their authors or adaptations will be requested as indicated in a personal letter.
