correspondence analysis

Statistics

A technique, proposed by Hartley in a 1935 paper, that results in the display of data from a contingency table in a scatter diagram that includes points representing row categories and points representing column categories. If row points are positioned near each other in the diagram then this implies that the patterns of counts along those rows are very similar. The same applies for groups of column points. If a row point and a column point are positioned close to one another then this implies a positive association between the two. The calculations involved resemble those for principal components analysis.

Computer

A method of multivariate analysis popular in France and developed by J. Benzecri. The purpose of the technique is to rearrange the rows and columns of a data matrix so that units and variables with similar properties appear together giving rectangular blocks of similar values. The results may also be displayed graphically.
