Notes:

1. Estimated coefficients shown here were derived using the bi-weight method (see Appendix).
2. There are no estimated coefficients for ages 1–4 by design. Since ₅q₀ is an input to the model, the age group 1–4 is excluded when fitting the model. After using the model to estimate mortality for age 0, we derive the mortality level for ages 1–4 as a residual component of ₅q₀. This procedure assures that the input and output values of ₅q₀ are identical.
