Topic Analysis
The Topic Analysis, Rotated SVD option performs a varimax rotation on the partial singular value decomposition (SVD) of the transaction item matrix. See Singular Value Decomposition. You must specify a number of rotated singular vectors, which corresponds to the number topics that you want to retain from the transaction item matrix. After you specify a number of topics, the Topic Analysis report appears.
