Hi jelm

You will need to post the questions if you expect someone to help you answer them...

Re: Z scores

Hi jelm;

Welcome to the forum. Why hate it? It is a beautiful field.


In mathematics, you don't understand things. You just get used to them.
90% of mathematicians do not understand 90% of currently published mathematics.
I am willing to wager that over 75% of the new words that appeared were nothing more than spelling errors that caught on.
