## P557 : Representation Of Structure In Psychological Data

### Class Description

Theory and application of quantitative methods for representing patterns implicit in matrices of psychological proximity data. Emphasis will be given to the analysis of nxn matrices of data on the similarity or confusion between all pairs of n objects, using two-way and three-way multidimensional scaling, clustering techniques, choice theory, signal detection theory, and probabilistic scaling methods.
