[R-sig-Finance] Mixture

[Krishna Kumar]

This looks like a parameter mix distribution.  Si a binomial distr with 
parameters (N,p)  where the parameter N
now is **not** fixed but varies as poisson with intensity say lambda. 
Then we have a new distribution which is poisson with intensity (lambda*p) 
[so mixture =a conditional distribution given the parameter and the 
distribution of the parameter itself ]

I vaguely think this may be possible with the distrEx package.

Best,
Krishna
