The gaussian distribution is not skewed.

If you mean the so-called "shew-normal" distribution
http://azzalini.stat.unipd.it/SN/
The pdf, can be calculatated as a product of two NORMDIST calls, as shown in
http://azzalini.stat.unipd.it/SN/Intro/intro.html
The cdf cannot be easily calculated using solely native Excel functions

If you are up for translating from Fortran to VBA, you would find
http://www.jstatsoft.org/counter.php...i05/t.pdf&ct=1
to be helpful in implementing Azzalini's formulas. I would also recommend
using the Smith library of probability functions

instead of native Excel functions

How does one come up with a gaussian formula using normdist and mean
and sigma provided?
I know how to create a normal distrib but dont know how to move
forward on a gaussian.....thanks, v- Hide quoted text -

Looking for a gaussian curve that is skewed and not a uniformly shaped
normdist curve. any takers?
