What for?

lifelib models are highly versatile and transparent. You can customize lifelib models and utilize them in various practical areas, such as:

  • Model validation / testing
  • Pricing / profit testing
  • Research / educational projects
  • Valuation / cashflow projections
  • Asset-liability modeling
  • Risk and capital modeling
  • Actuarial modernization to replace spreadsheet models

Why lifelib?

lifelib models are built using modelx, an open-source Python package for building object-oriented models in Python. By using lifelib, you can enjoy the following advantages:

  • Models run fast!
  • Formulas are easy to read
  • Easy to trace formula dependency and errors
  • Formulas are instantly evaluated
  • Pandas and Numpy can be utilized
  • Object-oriented
  • Input from Excel and CSV files
  • Documents can be integrated
  • Formulas are saved in text files

Consequently, you can expect following benefits from model development and governance perspectives:

  • More efficient, transparent and faster model development
  • Model integration with Python ecosystem (Pandas, Numpy, SciPy, etc..)
  • Spreadsheet error elimination
  • Better version control / model governance
  • Automated model testing
