Dear jarrod
we do this all the time in the two stage analysis of variety trials where
we have weights in the analysis, see the paper by Smith Cullis and
Thompson (2005) J Ag Sci Camb

Anyway the syntax would be

where wt contains the vector of 1/sqrt(sd_i)

I think this should do the trick@
let me know how you get on

warm regards
