Multiple Decrement Life Tables

  • More than one type of exit

  • Types of exit are mutually exclusive and exhaustive

    • “Competing risks”


Problems that mdlts can address l.jpg
Problems that MDLTs can address:

  • What is the probability that a 20 yr old will eventually die of heart disease?

  • How many years does cancer subtract from our life expectancy?

  • What would have been the effect of eliminating smallpox in 19th century UK?

Creating a period MDLT(See Box 4.1 on p. 77)

  • Prepare a basic life table

  • Take the nqx series from that table and apportion it to various causes of decrement

  • Compute the number of decrements from cause i in each interval

    4. Compute the number of persons aged x* who will eventually leave the table from cause i.


Notation l.jpg
Notation

nqix = (n × nmix ) / {1 + (n-nax)(nmix + nmx-i)}

nqix = nqx × (nmix / nmx )

= nqx × (nDix / nDx)

ndix = nqix × lx

lix = Σ ndia


Dependence l.jpg
Dependence

  • nqix = (n × nmix ) / {1 + (n-nax)(nmix + nmx-i)}

  • Holding nmxi constant, the higher nmx-i is the lower nqxi will be.

    • When nmx-i is higher, more of the potential victims of i will be carried off by other causes in the interval.


What if l.jpg
What if?

  • Associated single decrement life tables

    • Cause-deleted life tables

    • Section 4.4 provides detailed description of pros and cons of various approaches

  • BOX 4.2, p. 85
