摘要
一种可有双峰形状的概率密度函数（两种形式），有4个独立参数。导出了这个分布的数字特征，其分布函数的计算可利用正态分布表来进行。最后，给出了一个有关汽车车速分布的应用实例。
This paper proposes one new probability density function with several different shapesincluding bimodal shape. It has four independent parameters. Its distribution function value canbe calculated by using Normal distribution Table. The paper derives mean and variance of thedistribution. A real example involving automotive speed distribution is given to illustrateapplication of the distribution.
