Multivariate methods were successfully employed in a comprehensive scientometric analysis
of geostatistics research, and the publications data for this research came from the Science Citation
Index and spanned the period from 1967 to 2005. Hierarchical cluster analysis (CA) was used in
publication patterns based on different types of variables. A backward discriminant analysis (DA)
with appropriate statistical tests was then conducted to confirm CA results and evaluate the
variations of various patterns. For authorship pattern, the 50 most productive authors were
classified by CA into 4 groups representing different levels, and DA produced 92.0% correct
assignment with high reliability. The discriminant parameters were mean impact factor (MIF),
annual citations per publication (ACPP), and the number of publications by the first author; for
country/region pattern, CA divided the top 50 most productive countries/regions into 4 groups with
95.9% correct assignments, and the discriminant parameters were MIF, ACCP, and independent
publication (IP); for institute pattern, 3 groups were identified from the top 50 most productive
institutes with nearly 88.0% correct assignment, and the discriminant parameters were MIF,
ACCP, IP, and international collaborative publication; last, for journal pattern, the top 50 most
productive journals were classified into 3 groups with nearly 98.0% correct assignment, and its
discriminant parameters were total citations, impact factor and ACCP. Moreover, we also analyzed
general patterns for publication document type, language, subject category, and publication
growth.
