STAT134/150: Marginal distr. of a random var. w/ random var. param., given distrs
Hello,
I am a little shaky on my probability, so bear with me if this is a dumb question...
Anyway, the distributions of the two random variables are given:
[tex]X : Poisson (\lambda[/tex])
[tex]\lambda : Exp. (\theta)[/tex]
I simply need the marginal distribution of X and the conditional density for [tex]\lambda[/tex] given a value for X
I have all the equations for dependent distributions, but do not know how to apply them to this ostensibly easy problem...
Any help?
