Hi, I added high precision floating point support to the markov functional model making use of NTL (and supplementary boost functions). This allows for a better numeraire fit to long term (like say 50y) constant maturity calibration sets. NTL is only used for some intermediate results, the interface does not change. While there are other, faster yet dirty ways to stabilize the calibration (like the AdjustYts option) this is probably a good way to produce benchmark results and check convergence in the numerical parameters. I updated the code on my github as well as the doc on ssrn giving an example. More generally, is high precision arithmetic a topic anyone came across in some context he or she wants to share ? Peter |
