Term Structure of Volatility Calibration
This code optimises the parameters for the term structure of volatility (TSOV) applied to historical forward curves - see discussion in Harris in reference 1 below.
TSOVs avaible are:
TermType - 1 = sigma = A exp (-CT)
- 2 = sigma = A exp (-CT) + D
- 3 = sigma = (A + BT) exp (-CT) + D
Required data - Local volatility and return data - both assumed annualised.
The optimisation applies the nonlinear least square fitting tool and MLE approach using the fminsearch function - see reference 2.
To run type: TSOVControl
This code can be used to derive TSOV parameters for the Clewlow and Strickland Forward curve or spot models.
