Transition and measurement noise correlation in affine and Gaussian models: the case of oil prices

International Journal of Financial Markets and Derivatives (IJFMD), Vol. 8, No. 1, 2021

Abstract: This paper proposes a new approach for the estimation of affine and Gaussian factor models with the Kalman filter method. It considers the correlation between the innovations of transition and measurement equations. We use crude oil prices in the analysis. When applying this correlation approach in two- and three-factor models, we obtain improvements of error measures between estimated and observed future prices with inexpensive estimation procedures.
