Study illustrates various significant aspects like –types and trends of authorship, author productivity, degree of collaboration, collaborative index, geographical diffusion and institutional diversification of authorship. Findings suggest tangible growth of Informetrics literature over the years with predominantly multi-authored contributions. Result also show that Informetric research is unevenly scattered among 251 institutions from 38 countries around the globe.

It examines authorship pattern, collaboration trend among authors, predominant areas of statistical research, and time lag in publications. Subsequent analysis focuses on prolific
contributors, degree of collaboration, collaboration density, active sub-domains of statistics and time lag trend. Findings reveal the following: (a) the number of articles reduced from 24.6% to 14.0% that conforms to the growth trend of statistical publications in India; (b) single-authored paper counts only 30%, the rest in collaboration either by two-authors (47%) or three-to-five authors (23%) and average authorship accounts for 1.96 per paper; (c) contributors of Sankhyā worked in highly collaborative manner and the degree of collaboration (CC=0.698) is quite significant; and (d) most of the bilateral and multilateral collaborations has emanated from 12 institutions of 5 different countries. Ranked list of prolific authors has been carried out using fractional counting method. It is observed that author productivity is not in agreement with Lotka’s law, but productivity distribution data partially fits the law when the value of a approximated to 2.77 and the number of papers does not exceed two. Broad subject clusters, such as statistics (153)
and probability theory (38) constituted about 96% of the contributed articles. Nonparametric inference (18%), parametric inference (15%), design of experiments (10%) and multivariate analysis (8%) are found to be active areas of research in Statistics. The study shows an average time lag of fifteen months to publish an article, and a declining trend of time lags following second-degree polynomial type has been observed in this scholarly journal.

Critical examinations have been made on average citations occurred in each publication, various source materials cited, highly cited keywords, frequently cited journals, and identifying the core journals in statistical research. Bradfor’s scattering of cited journals (zonal distribution) has also been carried out. Findings reveal that an average of 18.84 cited references were appended in each publication, and thereby reinforces the proposition of discipline oriented citation behavior of scholarly literatures. The paper illustrates wide variety of source materials, where journal-articles get cited predominantly and the citation of web-resources is very poor; thus citation behavior of Sankhya exhibits a close resemblance with the usual practice of S&T journals. It suggests an average of five keywords to be transcribed by the authors in each article. The study identifies a total of 2732 journal-citations in 372 unique titles, thus journal citation density is derived as 7.35. In fact top 12 journals have contributed more than 50% citations, subsequently top five (core journals) received more than one-third (34%) of the total journal-citations. Annals of Statistics is the most highly cited journal; followed by JASA, Biometrika, JRSS-B, and Annals of athematical Statistics. Bradford’s plot (cumulative citations vs. logarithm of journal ranks) presents a deviation of classical S curve. Above all Sankhya could stake claim as one of the most authoritative source of scholarly literatures on statistics and allied areas of research.

Findings reveal that - publication output doubles over the study period as article publications increase considerably; though single-authored contributions were significant (30 %), majority of contributions were collaborated by two-authors (36 %), while average authorship accounts for 2.28 per communications. Degree of collaboration (DC) was impressive (0.699) but not overwhelming as research collaborations has emanated from 199 higher learning institutions of 32 countries across the globe. Ranking of prolific contributors has shown Prof. Egghe on the top followed by L Bornmann; R Rousseau and L Leydesdoff. Result also shows upward trend of keyword usage with an average of 4.55 per items, of which h-index, citation analysis, bibliometrics, g-index, etc, expectedly predominates. Scholarly nature of source journal has been further ascertained from increasing citations and reference usage trend. Moreover, growing hardness
of the field has been attributed to JOI due to the increasing usage of tables and figures. Study also showed that the journal takes an average of about four month time to publish a manuscript."
