genRoc

Input

Disease prevalence in population. The proportion of a birth cohort that will get disease in their lifetime.
Heritability of liability. The proportion of variation in phenotypic liability attributed to additive genetic effects.
Increased risk of disease in siblings of affected relatives. We assume that this increased risk reflects only shared genetic risk. Max risk constrained to have \(h^2_L \leq 1\). (as per equation 1 in the original publication.)

Optional

AUC estimated by user from genetic risk score predicting case-control status. If not provided \(h^2_{L_{[x]}}\), \(\rho_{\hat{G}G}\), \(\lambda_{s_{[x]}}\) and \(\frac{ \lambda_{s_{[x]}} - 1 }{ \lambda_{s} - 1 }\) are not calculated.
