Re: Normal Probability Integration

Hi;

I do not think those are doable.


In mathematics, you don't understand things. You just get used to them.
Of course that result can be rigorously obtained, but who cares?
Combinatorics is Algebra and Algebra is Combinatorics.

Yes, they are. Recall Normal probability distribution, please.

Re: Normal Probability Integration

The integral of the Normal distribution yields the error function. The error function is not an elementary function. In other words the integral does not have a closed form.

Yes, they are.

I do not think so and neither does mathematica or maple. I am willing to look at your answer. Please provide your answer.

Re: Normal Probability Integration

Doesn't that have two parameters not one? That is why I asked.

Re: Normal Probability Integration

That is usually given a number, example Normsdist(2). I have no idea what it means when a function is put in there.
