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:
http://en.wikipedia.org/wiki/
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.
Thanks,
Mike
