Standard errors of sexual dimorphism?
...ferent
traits in four populations (a total of 28 SD-estimates). We have used the
following formula for estimating SD: 100 * (mean male trait value - mean
female trait value)/overall trait mean).
Then, we have used these SD-estimates to perform a GLM against other
interesting variables, such as the intersexual genetic correlations for each
of the traits.
Here are my questions:
1. Is there any procedure in "R" you would recommend that takes in to
account the sampling variance of the SD-estimates, rather than using the
mean value of each (which is supposed to reduce error and increase Type

Question about random interactions in MCMCglmm
Hi,
I've been a bit confused by different wyas we specify random effects
in lmer and MCMCglmm i just want to clear something. When I want to
look for intersexual genetic correlations in the trait, is it
equivalent to treat this trait for opposite sexes as separate traits
and include the term idh(trait):animal - to treating this as a single
trait and fitting idh(sex):animal? Do these two ways of specyfying
random effects differ in this case?
Cheers,
sz.
