ExtendedCoxIngersollRoss::Dynamics Class Reference
#include <ql/models/shortrate/onefactormodels/extendedcoxingersollross.hpp>
Detailed Description
Short-rate dynamics in the extended Cox-Ingersoll-Ross model.The short-rate is here
where is the deterministic time-dependent parameter used for term-structure fitting and
is the state variable, the square-root of a standard CIR process.
