计算各种分布函数的分位数，比如F分布、T分布、正态分布、BETA分布-Calculate the sub-distribution functions of various bits, such as the F distribution, T distribution, normal distribution, BETA distribution

本程序可通过概率求标准正态分位数，亦可通过正态分位数求标准正态分布的累积概率-The program by the probability of seeking standard normal quantile, and also through the the normal quantile seeking a standard normal distribution cumulative probability

利用VB编程，实现计算标准正态分布的分位数，方便快捷！-inverse normal distribution
