Brief comparison to Roberts et al. Jonathan Dreyfuss, Boston University 6 August 2012 <p>I hope you enjoy our article and welcome any questions/comments. <br/> <br/>One question I have received is how our paper relates to Roberts et al. . Our article does not discuss their work, because we submitted approximately half a year before Roberts et al. came out. Briefly, Roberts et al. had a similar goal to ours: they tried to identify genetic prediction bounds without imposing a form on the risk distribution. However, Roberts et al.’s approach was found to be inferior to the liability-based analytical approximation, because Roberts et al. (a) do not account for identical twins’ shared environment (the liability-based approximation, and our method, use heritability to account for this), and (b) present "absolute upper bound[s]" that are lower than those from the liability-based approximation . In turn, we directly compare the liability-based approximation to our method, and we show that the liability-based approximation's upper bounds are lower than ours. Thus, we feel that our paper does not suffer for lack of a comparison to Roberts et al. <br/> <br/>Sincerely, <br/>Jonathan M Dreyfuss <br/> <br/>References <br/> N. J. Roberts, J. T. Vogelstein, G.
