Returns the probability from a Poisson distribution.
-
m
-
is a numeric mean parameter.
| Range: |
m ![[ge]](../../../../common/63294/HTML/default/images/ge.gif) 0 |
-
n
-
is an integer random variable.
| Range: |
n 0 |
The POISSON function returns the probability
that an observation from a Poisson distribution, with mean m,
is less than or equal to n. To compute the probability that an
observation is equal to a given value, n, compute the difference
of two probabilities from the Poisson distribution for n and n-1.
