Comparison of model fit quality, point estimates and confidence intervals for the statistical models ${\mathbf{f}}_{j,\ell }\sim {\mathbf{p}}^{(j)}\left(t_{\ell }\right)+𝓝\left(0,N_j^{-1}{\mathbf{S}}^{(j)}\left(t_{\ell }\right)\right)+𝓝\left(0,{\omega }^2\mathbf{I}\right)$ (Model I) and ${\mathbf{f}}_{j,\ell }\sim {\mathbf{p}}^{(j)}\left(t_{\ell }\right)+𝓝\left(0,{\omega }^2\mathbf{I}\right)$ (Model Ia) applied to publicly available cell fraction data from Yang et al. [17].
