#' @description
#' The Russett data set (Russett, 1964) is studied in Gifi (1990). Three
#' blocks of variables have been defined for 47 countries. The first block
#' is related to "Agricultural Inequality", the second to
#' "Industrial Development", and the last one describes the
#' "Political Instability". Russett collected this data to study
#' relationships between Agricultural Inequality, Industrial Development and
#' Political Instability. Russett's hypotheses can be formulated as follows:
#' It is difficult for a country to escape dictatorship when its agricultural
#' inequality is above-average and its industrial development below-average.
