in thread Calculating the inverse normal distribution

Hmm...that's not quite it. What I have is the standard Gaussian distribution with a known mean (0) and standard deviation (1). Let's call that G(x). I also have a fixed percentage, let's say 0.85. What I need to find is a point z such that integral(G(x), -infinity, z) = 0.85. Does that make more sense?

Be your own disciple, fan the sparks of will
For all of us waiting, your kingdom will come

[Lotus1]: Cosmic37 if you undef $/ in a local context to a block it won't affect the global version after the block finishes
[Lotus1]: or you can just do local $/ in a block
[erix]: cool
[Cosmic37]: thank you Lotus I understand
[Cosmic37]: now I have tried another blunder - can anyone explain why I am such a dunderhead?
