Project fastlife¶
This project includes the fastlife model. The firstlife model calculates the present values of the net insurance cashflows. The calculation results are the same as the model in Project simplelife. However, the fastlife model carries out the calculations for all model points in parallel at the same time, while the calculations in the simplelife model are done separately for each model point. Because the parallel processing is
The values of most Cells for projecting cashflows are pandas Series objects that contain calculation results for all model points:
>>> fastlife.Projection.PV_NetCashflow(0)

fastlife runs faster than simplelife thanks to powerful vector operations on pandas Series. The blog posts on https://modelx.io/blog linked below discuss the background and performance of fastlife.

How to use the project¶
Create a project folder from IPython in Spyder. as explained in Creating a Project section. Read the model in Spyder by following the steps in Reading a Model section.
The model become accessible
as fastlife global variable
in the IPython console in Spyder.
There is no explicit ‘Run’ command to run the model. The model calculates its values on the fly, when requested.
