I'm trying to understand the analysis used in a paper that has recently created a splash in Science:
Taylor, J., Roehrig, A. D., Hensler, B. S., Connor, C. M., & Schatschneider, C. (2010). Teacher quality moderates the genetic effects on early reading. Science, 328, 512-514.
They have used a moderator variable analysis described by:Purcell, S. (2002). Variance components models for gene-environment interaction in twin analysis. Twin Research, 6, 377-382.
This is in old Mx.
Am trying to track it down, but wondered if there is anything comparable in OpenMx?
