Hi
The sample mean is an unbiased estimator of the lambda parameter of the
poisson distribution.
You can use the Kolmogorov-Smirnov test to check that it is not unreasonable
to use the Poisson distribution. The syntax is
NPAR TESTS
/K-S(POISSON)= countvar
/MISSING ANALYSIS.

I have a set of count data, for which I would like to find the closest
fitting Poisson distribution.
How can I use SPSS to estimate the mean ?
