We propose kernel-based collocation methods for numerical solutions to Heath–Jarrow–Morton models with Musiela parametrization. The methods can be seen as the Euler–Maruyama approximation of some finite-dimensional stochastic differential equations and allow us to compute the derivative prices by the usual Monte Carlo methods. We derive a bound on the rate of convergence under some decay conditions on the interpolation functions and some regularity conditions on the volatility functionals.

具有 Musiela 参数化的 Heath-Jarrow-Morton 模型的基于核的搭配方法

我们提出了基于核的搭配方法,用于使用 Musiela 参数化的 Heath-Jarrow-Morton 模型的数值解。这些方法可以看作是一些有限维随机微分方程的 Euler-Maruyama 近似,并允许我们通过通常的 Monte Carlo 方法计算衍生价格。我们推导出在插值函数的一些衰减条件和波动率函数的一些规律性条件下收敛速度的界限。
