We report a change in the method of averaging parameters of the Siler mortality model fitted to a series of Old World monkey survivorship schedules. Substitution of geometric for arithmetic means of multipliers of exponential terms avoids incorrect weighting of parameters. These changes have minor effects on the composite standard mortality schedule for these animals originally described in 1988. © 1993 Wiley‐Liss, Inc.
