Hi all,

Looking to calculate the expected mean and variance of a ratio  
distribution where the source distributions are gaussian with known  
parameters and sample values are correlated. I see (from wikipedia:  
Ratio_distribution#Gaussian_ratio_distribution) that this calculation  
is quite involved, so I'm hoping that someone has already coded a  
function to achieve this.
