Gaussian Distribution
The Gaussian distribution
is defined as the normal distribution
- a bell-shaped function. The normal distribution (the term first used
by Galton, 1889) function is determined by the following formula:
f(x) = 1/[(2*p)1/2
* s] * e**{-1/2*[(x-m)/s]2}
-∞ < x < ∞
where
m |
is the mean |
s |
is the standard
deviation |
e |
is the base of the natural logarithm, sometimes
called Euler's e (2.71...) |
p |
is the constant Pi (3.14...) |
