Rarified Chi-squared analysis of PN and PPN survivorship of cattle and suids at Sha'ar Hagolan.

The Chi-squared values and significance in the rightmost columns refer to the 2×2 cross-tabulation of cattle and suid fused and unfused skeletal elements appearing in the central columns, arranged by period (PPN, top; PN, bottom). The “fused” and “unfused” frequencies in the central columns are cumulative and include all the specimens that fuse by the age listed in the leftmost column. The decomposition of the survivorship rates into this rarified Chi-squared design demonstrates that there is clear dissimilarity between cattle and pig survivorship in the PN. Dissimilarity cannot be demonstrated for PPN survivorship.
