#### TYPICAL OBJECTS OF TYPE Hull White Model

This type represents a short rate that follows a single-factor stochastic process

**according to the SDE:**

*r*

*dr = (θ - αr)dt + σdw*where

**is a Wiener process,**

*w***and**

*α***are constants and**

*σ***is a deterministic function of the time**

*θ*

*t*It follows that the short rate follows a gaussian process with a mean reverting stochastic drift, a fact that results in being normally distributed. Web reference available here
