Average Percent Error (APE)
"Average percent error" (below), formulated by Beamish and Fournier (1981), reduces bias in error estimates by comparing individual estimates to the mean of the estimates, as opposed to comparing one estimate directly to the other. APE is commonly used by several age-reading labs in describing error. The Age Determination Unit uses this estimate for establishing species-specific control limits.
