## Detailed Description

Short-rate dynamics in the generalized Hull-White model.

The short-rate is here

f(r_t) = x_t + g(t)

where g is the deterministic time-dependent parameter (which can not be determined analytically) used for term-structure fitting and x_t is the state variable following an Ornstein-Uhlenbeck process.
