Account value to number of policies¶
This graph uses the
from 2. Extended Stochastic Example,
and shows path dependency of policy decrement.
The scatter plot shows how the number of policies at maturity varies by the level of account value at maturity, and the graphs on the sides show the distributions of the two factors.
