create Hull-White interest rate model
HullWhiteModel(theta, alpha, sigma)
observed term structure of interest rates
speed of mean reversion
The HullWhiteModel command creates a Hull-White model with the specified parameters. Under this model the short rate process r⁡t has the following dynamics with respect to the risk-neutral measure
where α and σ are non-negative constants and W(t) is a Wiener process modeling the random market risk factor.
