The combined likelihood of both components of the model is:  \[  \textrm{L}\left( D_{h} \left| \alpha_h, \textrm{L}\left(\alpha_h,  \beta_h, \Phi_\bullet, \eta_j, \Upsilon_\bullet \left| D  \right. \right) = \prod_i \left[ \Pr_{\mathrm{BNB}} \left( X = x_{ij} \left| \lambda_{hi}, \Phi_i, \eta_j \right. \right) \prod_k \Pr_{\mathrm{BB-mix}}\left(Y_{ik} = y_{ik} \left| p_{h}, n_{ik}, \Upsilon_i \right. \right) \right] \]  To test for an association with genotype we perform a likelhood ratio test that compares the alternative hypothesis $\alpha_h != \beta_h$ to the null hypothesis $\alpha_h = \beta_h$.
