Detailed Description

Short-rate dynamics in the Black-Karasinski model.

The short-rate is here

\[ r_t = e^{\varphi(t) + x_t} \]

where $ \varphi(t) $ 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.
