This is more of a historical related question. Edmond Halley in 1693 published an actuarial table showing mortality rates. The tables show yearly statistics for ages 1-84 and a summary statistic for ages 84-100. I have searched hard for the missing data, but with no luck (See also Geoffrey Heywood's article).
So this question has two parts:
- Can anyone point me to a different source showing the original paper?
- What would be the best model to generate the missing statistics between these years?
