The data was extracted from the National Council for Scientific and Technological Development that is an agency of the Ministry of Science and Technology in order to promote scientific and technological research and the training of human resources for research in the country.
The scientific production of each researcher is described by a set of 33 continuos numerical and 3 categorical variables (institute, area of knowledge and sub-area of knowledge). The continuos variables are averages of production values computed in three years (2006, 2007 and 2008) for each research.
The original data (first level of observation) are aggregated regarding the institute and sub-area of knowledge categorical variables generating a new data base of size 5630. These data represents new concepts of scientific production (second level of observation). After the aggregation each variable is represented by symbolic variable of type interval. The new data base is avaliable at this link (1,683 KB).
