Details

Nielsen used data on 39 different types of ornaments from Ørsnes (1966) to seriate a series of 77 Germanic Iron Age graves from Bornholm, Denmark (1988, Table 4 and Figure 7). Baxter re-analyzed the data to illustrate correspondence analysis (1994: 104-107, Table A6). These data were taken from Nielsen's Table 4 showing her seriation. Baxter's version is scrambled in order to evaluate different seriation methods and does not include the ornament types (illustrated in Nielson's Figure 7). The data include Ørsnes's period designation (1966).
