Filtering and Identification of Affine Term Structures from Yield Curve Data
نویسندگان
چکیده
We consider a slight perturbation of the Hull-White short rate model and the resulting modified forward rate equation. We identify the model coefficients by using the martingale property of the normalized bond price. The forward rate and the system parameters are then estimated by infinite dimensional Kalman filtering equations, coupled with the usual statistical techniques.

A Family of Selective Partial Update Affine Projection Adaptive Filtering Algorithms
In this paper we present a general formalism for the establishment of the family of selective partial update affine projection algorithms (SPU-APA). The SPU-APA, the SPU regularized APA (SPU-R-APA), the SPU partial rank algorithm (SPU-PRA), the SPU binormalized data reusing least mean squares (SPU-BNDR-LMS), and the SPU normalized LMS with orthogonal correction factors (SPU-NLMS-OCF) algorithms...
متن کاملIdentification of Affine Term Structures from Yield Curve Data
There is a vast literature [4, 8, 9] on estimating parameters of short rate models in finance. One popular approach is to take a short rate model that leads to an exponential-affine expression for the corresponding bond price. The yield is then easy to calculate. Artificial noises are then added to yields of different maturities and the maximum likelihood method is used to estimate the model pa...
متن کاملBeta Regimes for the Yield Curve
We propose an affine term structure model which accommodates non-linearities in the drift and volatility function of the short-term interest rate. Such non-linearities are a consequence of discrete beta-distributed regime shifts constructed on multiple thresholds. We derive iterative closed-form formula for the whole yield curve dynamics that can be estimated using a linearized Kalman filter. F...
متن کاملEfficient elliptic curve cryptosystems
Elliptic curve cryptosystems (ECC) are new generations of public key cryptosystems that have a smaller key size for the same level of security. The exponentiation on elliptic curve is the most important operation in ECC, so when the ECC is put into practice, the major problem is how to enhance the speed of the exponentiation. It is thus of great interest to develop algorithms for exponentiation...
متن کاملAn International Examination of Affine Term Structure Models and the Expectations Hypothesis
We examine the yield curve behavior and the relative performance of affine term structure models using government bond yield data from Canada, Germany, Japan, UK, and US. We find strong predictability of forward rates for excess bond returns and reject the expectations hypothesis across all five countries. A three-factor model is sufficient to capture movements in the yield curve of Canada, Jap...
