- Abstract
- This paper compares the method of Correspondence Analysis (CA) for finding patterns in archaeological sites by artifacts abundance data, with a robust variant, named Taxicab Correspondence Analysis (TCA). We show that this comparison is useful, especially for sparse tables with outliers. We identify three kinds of outliers. Three well-known datasets are reanalyzed.
