Figure 6.

Age versus fitted menstrual cycle length for six women with more than 40 repeated measurements with addition of 95% credible interval (dashed line), 80%, 95%, and 99% forecast intervals for their next cycle, and observed menstrual cycle length (points) using the model $y_{\mathit{ij}}=m_{\mathit{ij}}+{\gamma }_{\mathit{ij}}+c_{\mathit{ij}}$, when dropping the term $r_{\mathit{ij}}$ from the model. The estimated concordance correlation coefficient (CCC), and Pearson correlation coefficient (r) between fitted and observed values are reported for each woman. Accuracy ($C_b$) can be obtained using ${\text{C}}_{\text{b}}=\text{CCC}/\text{r}$.
