Fig. 3From: Modeling of atrophy size trajectories: variable transformation, prediction and age-of-onset estimationOptimization using NPML approach. Log-likelihood values obtained from fitting Model (2) to the analysis data set with the NPML method, as implemented in the R package boxcoxmix [21]. The black line indicates the optimal values of the transformation parameter λ for varying numbers of mass points K. The corresponding values can be found in Table 2Back to article page
