Project nestedlife¶
The nestedlife project has the same annual projection
model of basic traditional life policies
as simplelife, but at each projection step,
a nested projection going forward from the step is carried out.
The outer and nested projections share the same base assumptions, but
the assumptions of the nested projections can be adjusted based on how
the outer projection develops up to each projection step at which point a
nested projection starts.
The main purpose of this model is to simulate actual/realistic cashflows as the outer projection, and expected future cashflows at each projection step as each of the inner projection.
Model Structure¶
Composition Structure¶
Input Space and Economic Space hold
input data read from input.xlsx. LifeTable Space
is the same is the one in simplelife, and calculates
commutation functions and actuarial notations.
BaseProj, and PV serve as
base Spaces for OuterProj
and InnerProj.
OuterProj is for carrying out outer projections,
As is the case of simplelife,
The OuterProj is parametrized with PolicyID,
so Projection[1] represents the Projection Space for Policy 1.
The present values of the cashflow items are also calculated in
the OuterProj Spaces.
For example, the expression
nestedlife.OuterProj[1].PV_NetCashflow(0)
returns the present value of net cashflows for Policy 1.
