Given Excess LDF for Lower Retention, Find Excess LDF for Higher Retention
- LDF = d * (x / k)(qi-qj), where
- 1. d = the excess LDF at the lower retention
- 2. x = the new higher retention
- 3. k = the lower retention
- 4. qi = Single Parameter Pareto q at earlier age
- 5. qj = Single Parameter Pareto q at later age
