Parameter estimates for the best model.

Parameter estimates for α, λ, and ω (95% confidence bounds in parentheses based on likelihood profiles, [42]) derived from the best model (i.e., model VII, Table 3) for explaining senescence variation. The α parameter represents the shape of the Weibull hazard function, λ represents the magnitude of the Weibull hazard given the shape of the function, and ω is a derived parameter that provides a shape-adjusted index of the rate of senescence [26].
