Poisson function. Integration OFF.
A model expressing the ratio of two Poisson distributions of
mean mu, one for which the random variable is x, and the other
for which the random variable is equal to mu itself:
f(x) = A (mu!/x!) mu^(x-mu)
POISSON Parameters
1 | mean | mean mu |
2 | ampl | amplitude A |
See "ahelp integrate" for further information about
source model integration.
