Right mathman (and of course to everyone else), I am actually interested in finding what the bounds would be for the correlation but then [I thought] I first need to solve for the covariance. So, the reformed question is: What are the bounds (maximum and minimum) for the correlation based...

Can someone please advise or give a comment or ask for more information if my question is not clear? I urgently/desperately need to know if this is solveable and how? Many thanks in advance, George

Dear All, The bivariate Poisson distribution is as follows, \[ f(y_{s},y_{t})=e^{-(\theta_{s} + \theta_{t}+\theta_{st})}\frac{\theta_{s}^{y_{s}}}{y_{s}!}\frac{\theta_{t}^{y_{t}}}{y_{t}!} \sum_{k=0}^{min(y_{s},y_{t})} \binom{y_{s}}{k} \binom{y_{t}}{k}...
