Hi Joe - That is very kind of you, and I really
appreciate it. I really didn't mean to put you out though - just thought
that possibly you might know of another good site. I have found some pretty
thorough statistics sites, but it can get a bit mind-numbing after a
while trying to work through some of the "proofs" - pages of complex
formulas leading up to the final result Other sites are very brief,
maybe offering a formula without much of an explanation. Still looking for that
perfect site - somewhere in the middle. Maybe we can talk the algebra lady
into adding statistics 8 - 0
Anyway, I would be very happy to learn from you if
you actually think it is something that you might enjoy. Otherwise, I know you
must be very busy, what with trading, developing systems, hosting
foreign dignitaries 8 - ) ...and who knows what else...
No need to worry about offending me
- I know when someone is being helpful... 8 -

Re QP, I did use it for a while but now I
have switched back to TC2K - so if your list is strictly for QP
talk then I probably wouldn't be able to add much - Dan accomplished
more with them in a month than I did in a year! But, if your
group includes AB talk, then I would be happy to sign up!
OK, that's about it for now - have a safe
trip!
Steve

Hi Steve - Wanted to acknowledge that I got your note
and will see what I can work up.
Many years since my engineering school, in fact 40
yrs?????? I'll see what I can find for
you.
Only request is that if it seems like I'm talking
down to you don't be offended, since I'll start from the beginning.
I was futzing around with the log after your question
and had to review it myself. A key item
is the natural number e which seems to find a place in
many things.
I'm going to be traveling tomorrow for about 5 hours so
it will take a while before any content comes your way.
BTW, you are a QP3 user aren't you? If so would you
like to join our little birds of a feather group
from the conference. We got together for lunch and mostly just go
to know each other. I've started
an Email distribution that we'll use to share or commiserate.
Best regards
Joe

Hello again Joe,
I have had a chance now to take a good look at
the site you provided below, and have bookmarked it. It is a great site for
brushing up on algebraic stuff ( I haven't been to school for a few years
now 8 - ). Would you by any chance know of a similar
site for statistical stuff - i.e., simple to understand? Not
asking you to search of course, I have already done plenty of that,
just wondering if you might already have something good. Thanks very
much!
Steve

Steve - log(apen/apeo) is the same thing
in AFL.
Only if you more than you probably wanted to know
but read on -
Tomasz chose to implement the natural log function
and name it log() and he notes that in the docs and apparently
is a common practice now a days. So ln () is used
to refer to the natural log of a number, that is base e (2.71828). A
little bit of history about Napier the Frenchman who invented logarithms
for rapid cannon ball trajectory calculations, is also how a slide
rule works adding logarithms represented by length.
Hope this helps
JOE

Hi,
In the formula for S&C Traders
Tips, 4/2006, "Avg Peak Excursion", we have this line:
Alpha = ln( APEN/APE0 ) / ln ( N );
I can't find any
reference to this ln() function in any of the docs. Could anyone tell me
what this is? I don't subscribe so I can't read the article. Thanks very
much!
Steve
