[R-sig-ME] distribution for ratios?

[Celine Teplitsky]

Dear all,

we are trying to run a meta-analysis on factors affecting heritability 
in MCMCglmm. As it is a ratio of 2 variances, the values are bounded 
between one and zero, but can not be interpreted as Success/NbTrials, so 
we can not use a binomial distribution.

So the trouble we're having is knowing which distribution to use? Should 
we just use a Gaussian?

Many thanks in advance for your help

Best regards

Celine
