摘要

我们得到了方差-伽马分布的累积分布函数的精确公式，即涉及修正的第二类贝塞尔函数和修正的第一类洛梅尔函数的无穷级数。根据这些公式，我们推导出两个相关零均值正态分布随机变量乘积的累积分布函数的精确公式。

ON THE CUMULATIVE DISTRIBUTION FUNCTION OF THE VARIANCE-GAMMA DISTRIBUTION

We obtain exact formulas for the cumulative distribution function of the variance-gamma distribution, as infinite series involving the modified Bessel function of the second kind and the modified Lommel function of the first kind. From these formulas, we deduce exact formulas for the cumulative distribution function of the product of two correlated zero-mean normal random variables.
