Hi, all.
My work involved in some probability calculation, which needs the quantile function of distributions like standard normal and t. However, I looked into scipy.stats.t, there's only pdf and cdf functions, and didn't see quantile function. What can I do with this problem? stats.norm.ppf stats.t.ppf gives the quantiles for a specific values (can be list or array)
.isf is the quantile for the survival function, and is for some distributions more precise for upper tails than using ppf.

I want your help, thanks a lot !
