### 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.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

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

X'(y-Xβ)=0

### 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.

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

Normsdist in Microsoft Excel

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