| Abstract: | In option pricing, it is very important to choose the model of underlying asset. Its choice is not only similar to the reality, but also easy to be simulated. In this paper, we focuses on the extended form of a class of O-U process used in 1 ], presents its analytical solution and specifically calculates its numerical characteristics, at last points out that its limit process is our familiar process-geometric Brownian motion. |
