(Vasicek) model By Thijs van den Berg | Published: May 28, 2011 In this article I’ll describe two methods for calibrating the model parameters of the Ornstein-Uhlenbeck process to a given dataset. The least squares regression method maximum likelihood method Introduction The Vasicek calibration is an important aspect of the Vasicek interest rate model. To calibrate the model, analysts typically perform a simple ordinary least squares (OLS) regression using actual daily interest rate data. This is needed to determine a, b, and sigma in the model.

The extended Vasicek model (also called generalized Vasicek model) with time-dependent parameters belongs to the group of time-inhomogeneous models (Fan, Jiang, Zhang, & Zhou, 2003). This model has been extended by the Hull and White by allowing both, the drift and variance coefficients, to be time-varying and its SDE is given by the formula (Fan, Jiang, Zhang, & Zhou, 2003) :

It was introduced in 1977 by Oldřich Vašíček, and can be also seen as a stochastic investment model. In this paper we calibrate the Vasicek interest rate model under the risk neutral measure by learning the model parameters using Gaussian processes for machine learning regression.
