The general objective of ASSO was to design methods, methodology and software tools for the analysis of multidimensional complex data (numerical or non numerical) coming from very large databases in statistical offices and administrations. Symbolic analysis extends statistical data analysis methods to more complex objects. Individuals processed by these methods are complex in the sense they represent groups of individuals, featuring variation among each group of individuals. Within the context of the project, the complex objects are called symbolic objects. The aim of the ASSO project was to improve the software built previously in order to render it more operational and attractive following users requests, to add new innovative methods and to meet needs of statistical offices.
