Re: And now what?




The normal nexty step would be to transform from the underlying scale
to the p scale using  zz/pq  where p is the average incidence,
q=(1-p)  and zz is z-squared where z is the ordinate of the Normal curve 
corresponding to the proportion.  So if p=0.5,  z=..399 and the factor is .64

  H2 on the underlying scale is  .499917/1.499917 = .3333
  so h2 on the p scale is  0.21
  
  You can get the variance of h2 from asreml (.pin file)
  and scale it similarly.
