理论模型

The general diffusion process can be obtained as a limiting case, so that we have a unified framework in understanding existing models in option pricing theory, including the geometric Brownian Motion, the model of Constant Elasticity of Varianc, the Residual Volatility and term structure of interest rates. Our model is capable of demonstrating volatility smile and stable relative deviation from real data.
