[R-sig-ME] distribution for ratios?

[Celine Teplitsky]

Dear all,

thank you for your suggestions.

The bivariate analysis is unfortunately not an option: in 'older' models 
using parent offspring regression, only heritability is estimated, there 
are no estimates of Va or Ve.

Thanks again

Celine
