英文摘要:
Characteristic functions of several popular classes of distributions and processes admit analytic continuation into unions of strips and open coni around $\\mathbb{R}\\subset \\mathbb{C}$. The Fourier transform techniques reduces calculation of probability distributions and option prices to evaluation of integrals whose integrands are analytic in domains enjoying these properties. In the paper, we suggest to use changes of variables of the form $\\xi=\\sqrt{-1}\\omega_1+b\\sinh (\\sqrt{-1}\\omega+y)$ and the simplified trapezoid rule to evaluate the integrals accurately and fast. We formulate the general scheme, and apply the scheme for calculation probability distributions and pricing European options in L\\\'evy models, the Heston model, the CIR model, and a L\\\'evy model with the CIR-subordinator. We outline applications to fast and accurate calibration procedures and Monte Carlo simulations in L\\\'evy models, regime switching L\\\'evy models that can account for stochastic drift, volatility and skewness, and the Heston model. For calculation of quantiles in the tails using the Newton or bisection method, it suffices to precalculate several hundred of values of the characteristic exponent at points of an appropriate grid ({\\em conformal principal components}) and use these values in formulas for cpdf and pdf.

中文摘要:
几类流行的分布和过程的特征函数允许在$\\mathbb{R}\\subset\\mathbb{C}$附近的条带和开圆锥曲线的并集进行解析延拓。傅立叶变换技术将概率分布和期权价格的计算简化为积分的计算,而积分的被积函数在具有这些性质的域中是解析的。本文建议使用$\\ xi=\\ sqrt{-1}\\ omega\\u 1+b \\ sinh(\\ sqrt{-1}\\ omega+y)$形式的变量变化和简化的梯形规则来准确快速地计算积分。我们制定了一般方案,并在列维模型、赫斯顿模型、CIR模型和具有CIR从属关系的列维模型中应用该方案计算概率分布和定价欧式期权。我们概述了在列维模型、能够解释随机漂移、波动性和偏斜的状态切换列维模型以及赫斯顿模型中快速准确校准程序和蒙特卡罗模拟的应用。对于使用牛顿法或二分法计算尾部分位数,只需预先计算适当网格({\\em共形主成分})点的数百个特征指数值,并在cpdf和pdf公式中使用这些值即可。
