More Multivariate Statistical Techniques
a. Correspondence analysis (CA) can be used for research on the Internet.
b. CA uses the same distance formula as MDS or cluster analysis.
c. CA provides a perceptual map like MDS but the data can come from checklists.
d. CA provides a perceptual map like MDS but the points represent market shares.
e. both c and d are false
a. Correspondence analysis (CA) tracks the flow of correspondence, and these days
