ADE software: multivariate analysis and graphical display of environmental data In: GUARISO G.,RIZZOLI A. Software per l'ambiente Patron editore, Bologne, 1995, pp. 57-62. Abstract : ADE (Analysis of Environmental Data) software deals with the multivariate analysis of environmental data sets. ADE 4.0 comes from the combination of ADE 3.7 (.i.Chessel and Dolˇdec, 1993;), and MacMul and GraphMu (.i.Thioulouse, 1989, 1990;). In ADE software, a series of multivariate techniques permits to analyze several types of data (e.g., quantitative, qualitative, presence/absence). The examples incorporated in ADE for trial runs mainly deal with ecological questions. However, people from other disciplines (e.g., chemometry, sociology) and interested in the use of linear ordination methods should find in ADE software the most recent developments. They includes one-table, two-table, and K-table (k³3) techniques. ADE software benefits of the user-friendliness of the Macintosh computer (scrolling menu, graphical performance). Furthermore we have designed ADE for non specialists in multivariate analysis and computer sciences. People having a basic statistical background and routinely using Macintosh computers should be able to use ADE software without any difficulty.
