The subadult fertility formula contains a typo. The correct formula is as follows:

When this formula is applied to the skeletal populations from the Health in the Western Hemisphere project, Gross Reproductive Rate (GRR) estimates differed from those made using the Bocquet–Appel (1982) ratio on average by 0.98 offspring (range was 0 to 2.7). A revised version of Table 2 is provided. Calculations of GRR in rows 1 and 3 were corrected.
