Hi ElMaestro,

» In perspective, history has been somewhat cruel to anyone assume T=R for example in relation to power and sampe sizes. In other words, what is needed (if there is a need at all?!?) is a "Cauchy distribution with the equivalent of a noncentrality parameter", for lack of better wording.

but in the link above you can see
Uncorrelated noncentral normal ratio
...Under certain conditions, a normal approximation is possible...

Correlated noncentral normal ratio
...The offset result is also consistent with the "Cauchy" correlated zero-mean Gaussian ratio distribution in the first section...

Kind regards,
Mittyri
