[SciPy-User] poisson distribution in scipy.stats

[Davide Cittaro]

Hi all,
about the poisson generator... given l (expected) and k (found) I  
guess that the way to get the probability of k I have to do this:


d = scipy.stats.poisson(l)
p = pmf(k)

which I found being the same of

p = scipy.stats.poisson.pmf(l, k)

I've here some code in which it is written:

d = scipy.stats.poisson(l, k)
p = d.pmf(k)

which gives different results. Which is the right way to initialize  
the distribution (and get the PMF)?

Thanks

d
