Computing the Constant Elasticity of Variance Option Pricing Formula
将常数弹性方差期权定价公式用非中心卡方分布表示，从而能应用已知近似公式并推导出一类闭式解，还给出了一个简单高效的计算该分布的算法。
This paper expresses the constant elasticity of variance option pricing formula in terms of the noncentral chi-square distribution. This allows the application of well-known approximation formulas and the derivation of a whole class of closed-form solutions. In addition, a simple and efficient algorithm for computing this distribution is presented.
