Hello, I'm trying to get z score by a given probability value and I cant manage to do it. I tried the jStat.zscore function but it requires array and I need like a calculator that by a given p value I get the z score.

Just use

jStat.normal.inv( p, mean, std )

were p is the probability you require.

If you want a STANDARD z score then set

mean to 0 and std to 1.
