"The monograph is devoted to the problem of data aggregation in its various aspects from general concepts of adequate representation of numerous data in a concise form to practical calculations illustrated by applying abilities of R language. ... the students and researchers familiar with R can find the book to be a very friendly introduction to statistical approaches to the aggregation with interactions between variables." (Stan Lipovetsky, Technometrics, Vol. 59 (3), November, 2017)

Simon James completed his PhD on The use of aggregation functions in decision making under the supervision of Dr. Gleb Beliakov at Deakin University in 2010. Since then he has held a Lecturing position in the School of Information Technology. Before undertaking his PhD, he had completed a double degree in education and arts, providing a solid grounding in reflective teaching practice. He currently teaches mathematics to students across a range of undergraduate and post-graduate courses, including education, science, IT and data analytics. His research interests to date have included aggregation functions, fuzzy sets, group decision making and consensus, and the application of indices in ecology. He has authored over 40 journal and conference papers and has been an associate editor for IEEE Transactions on Fuzzy Systems since 2015.
