Simulations results : quantile-quantile plot for the parameter estimations, high separation setting, n=100. In black: censoring rate τ=0.5, in lightgray: τ=0.05. Results for Weibull scale, Weibull shape, mixed model intercept and mixed model slope, (ζ_1g,ζ_2g,β_0g,β_1g respectively form Eq. (8)) are presented. g={1,2}
