How to obtain row coordinates from Correspondence Analysis?
Resolution
When using the correspondence analysis module, it is possible to obtain row coordinates of observations used in the analysis. Both the Correspondence Analysis and Multiple Correspondence Analysis can provide column coordinates for the observations, but only the Correspondence Analysis can provide the row coordinates.
When analyzing very large samples,individual cases are not always of interest. If there are several thousand observations, the simple correspondence analysis of the indicator matrix is not convenient, and sometimes not possible. In those cases, the multiple correspondence analysis approach is much more efficient, but this analysis will not provide the row coordinates of the observations.
