Recenzje

"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)
