ExitTable#
ExitTable extends DecrementTable
for lapse / withdrawal tables. The governing decrement is the exit rate
\(o_x\), which represents the probability that a contract or member aged \(x\)
lapses, surrenders, or withdraws within one year.
Exit tables are used in persistency analysis, lapse-risk pricing, and
multi-decrement models for group pension and collective insurance products.
Table files carry \(o_x\) columns (prefixed ox_m, ox_f, or ox_u) and may include
generational improvement factors for cohort-based exit rates.

Inherited from DecrementTable#
The following members are inherited from DecrementTable.
See the DecrementTable reference for full documentation
of each member.
Note
qx is not available on ExitTable — the primary decrement is ox
(exit / lapse rate). Calling qx raises NotImplementedError.
