I don't understand why you assume I don't know what I'm talking about Is it because you don't know what degrees I hold?

No. I have no idea what your degrees are. But your argument is incorrect. Pure and simple. Now maybe as you had it with him it was different, buy a normal distribution is describe by it's mean and it's SD. That's all you need to construct it

I said that what the guy you are promoting claims is flat WRONG (on multiple levels but I chose to address the most basic aspect) He advises finance, where getting this stuff right is IMPORTANT You went in defense mode

Well if I did, it's because you attacked first...unless I'm the one who mentioned you first and started a thread on how you should update your understanding...

Here's a great writeup on some of the problems with Std as used in finance (more fine grained than the absolute basics we are for some reason debating) https://www.edge.org/response-detail/25401 …

Well yeah, I agree with this but in the general sense: What do these things actually measure? The paper didn't do a great job of convincing of why it shouldn't be applied to finance--at least anymore so than why any other method would produce "reasonable measurement"

Well, when your true underlying distribution is non normal, but you are using Std of normal distribution as your model, that mismatch can and does result in catastrophic losses.

Finance isn’t Physics, @EdLatimore, and assuming it is with bad models that assume uniform distribution leads to real-world blow ups that effect lots of people.
