Table 3.

Mean relative bias of catchability coefficient q₁ (and standard deviation) given δ_q = q₁ − q₂ bins, where q₁ is the catchability coefficient prior to the joinpoint, and q₂ is the catchability coefficient following the joinpoint, by scenario. Scenario 1–3 indicate analysis assuming no joinpoint, using the estimated joinpoint, or using the true joinpoint, respectively.

Bin	Scenario 1	Scenario 2	Scenario 3
δq ≤ −1.5 × 10−5	116.83 (2.58)	90.69 (1.67)	−1.80 (0.12)
−1.5 × 10−5 < δq ≤ −5.0 × 10−06	72.36 (1.49)	17.97 (0.83)	−6.48 (0.16)
δq > −5.0 × 10−06	68.06 (1.26)	−9.81 (0.27)	−10.22 (0.25)
