Beschreibungen/Notizen

• MapWise Version 2.03 from Market ACTION Research Software Inc. offers several proprietary enhancements that extend Levine's (1979) algorithm for correspondence analysis. As in any correspondence analysis, the program is predicated on maximizing interrelationships among numerical scores that are assigned to row and column categories in a data matrix. However, MapWise scales the axes on the basis of each axis' contribution to explained variance, thus eliminating the need for drawing vectors to interpret perceputal maps. MapWise offers a proprietary test of cell size by comparing correspondence and proximity maps of the same data. Since MapWise positions all points, active and passive row and column points, in Euclidean distance, the correspondence maps are interpreted like a road map.
