Authors Guidelines

Authors interested in publishing their articles are requested to send them via e-mail with an attachment file in Word or Latex to the following address:

The articles must be written in English. Authors are kindly requested to follow the style sheet.

Manuscripts must be organized in the following manner:

  • Title Page
  • Author’s Footnote
  • Abstract and Key Words
  • Article Text
  • Acknowledgments
  • Appendices
  • References

Author’s Footnote
The Author’s footnote should contain the institutional affiliation with complete address and email address. In case of co-authorship, a corresponding author must be indicated.

Abstracts and Key Words
The title should be followed by an English abstract. The abstract should summarize results, topics discussed, and main conclusions, but it should not contain any displays or complex mathematical notation, undefined abbreviations or references.

The English abstract is followed by three to five key words or phrases separated by comma which are used by Current Index to Statistics to index the article.

Article Text
Headings. The main body of the article should be divided by appropriate numbered section and subsection headings. Main headings are typed in uppercase letters. 
Sections and subsections must be cited in the main body of the article as Section. 

Abbreviations. Abbreviations should be defined at first mention and used consistently thereafter.

Acknowledgments. Acknowledgments of colleagues, grants, funds, etc. should be placed in a separate section before the reference list. The names of funding organizations should be given in full.

Appendices. Lengthy technical portions of a manuscript should appear in a separate appendix. A single appendix is headed "Appendix". If there are two or more appendices, they should be labeled " Appendix A", " Appendix B" and so on. Section headings, displayed equations, tables, and figures that are part of the appendix are numbered A.1, A.2, A.3, and so on (B.1, B.2, B.3 ETC.); if only one appendix, still use A.1, A.2, A.3, etc. All appendices must be cited in the main body of the article as "the Appendix" if only one and "Appendix A", "Appendix B" and so forth, if two or more.

Footnotes. Use of footnotes is discouraged; generally, their content is more appropriately incorporated in the text, placed in an appendix, or omitted entirely. Footnotes, when allowed, cannot contain elaborate mathematical notation, cannot be cued next to a mathematical symbol, and should be numbered consecutively.

Reference Citations. All references included in the References at the end of an article must be cited in the article text. For text citations, authors must use the author's surname and date of publication, according to the following style.

  1. A direct citation of a reference places only the date within parentheses:
    Gentleman (1978) explored this in greater detail.
  1. An indirect citation of a reference as an example places both the name and the date within parentheses with comma between them:
    Other recent suggestions include the use of Chernoff faces (Smith, 1980).
  1. When two or more works by the same author are cited together, do not repeat the name(s):
    Tukey (1965, 1980); Gilula and Smith (1971a,b) ; (Tukey, 1965, 1980)
  1. When citing several references within parentheses, place them in date order:
    (Smith and Smith, 1958; Tukey, 1965, 1980; Gilula and Smith, 1971a,b; Smith et al., 1974)

The first citation in the text to a paper with three or more co-authors should list all the names. Subsequent citations should give the first co-author’s name followed by “et al.”

Tables. Tables should be numbered consecutively in Arabic numerals following the order in which they are cited. Therefore, each table must be cited in the text. In page layout tables should be placed in sequence as close as possible to their first citation. Each table must have a brief descriptive title on top. The title should not duplicate information in the headings of the table. Each table must be keyed into the text as Table 1, Table 2 etc. 

Figures. Each figure must have a figure caption at the bottom, including the figure number. Figures are numbered consecutively, using Arabic numerals, and must be cited in the text. Each figure must be keyed into the text as Figure 1, Figure 2 etc.

Mathematical Material. Numbered mathematical expressions should be typed and centred on a separate line and identified by consecutive Arabic numerals in parentheses placed flush with the right margin. Only cited formulae must be numbered.

Please use the standard mathematical notation for formulae, symbols etc.:

  1. italic for single letters that denote mathematical constants, variables, and unknown quantities;
  2. roman for numerals, operators, punctuation, and commonly defined functions or abbreviations;
  3. bold for vectors, tensors, and matrices.

Reference list
A reference list should contain only references that are cited in the text; its accuracy and completeness are the responsibility of the author(s). References are alphabetized by authors’ surnames; two or more references of the same author(s) must be listed in chronological order. Journal titles should be given in full. The citing of references to unpublished material or publications which are not in the public domain should be avoided. References should be given in a standard form, as in the following examples:

Akaike H. (1974). A new look at the statistical model identification. IEEE Transactions on Automatic Control19, 716-723.

Crothers E. (1972). Memory structure and the recall of discourse. In R.O. Freedle and J.B. Carroll (Eds.), Language comprehension and the acquisition of knowledge (pp. 201-238). Washington, DC: Winston.

Kendall M.G., Stuart A. (1961). The Advanced Theory of Statistics, Vol. 2, Inference and Relationship. Hafner Publishing Co, New York.

Wold S. (1978). Cross-validatory estimation of the number of components in factor and principal component models. Technometrics, 20, 397-405.

Editorial style

In addition to content, manuscripts are judged on their clarity. Consequently, well-written and well-structured papers that will be of interest to a wide segment of readers are preferred.

Avoid common problems of style:

  1. use quotation marks only when a standard term is used in a nonstandard way and to indicate the beginning and ending of a direct quotation;
  2. italics are used to introduce important terms, when appropriate; they are to be used sparingly to indicate emphasis;
  3. abbreviations and acronyms should be minimized; those that are used are spelled out on their first appearance in the manuscript with the shortened form given in parentheses, for example, best linear unbiased estimate (BLUE).

Copies for authors
The authors will receive one copy of the journal and the pdf file of the article.
