TABLE 1.

Values of estimates ${\widehat{\mu }}_{ij}^c$ and associated standard errors for each time point t_{i j} = 1, … , 7 and class c = 1, … , 4. Standard errors are shown in parentheses. Note that the fitted values ${\widehat{\mu }}_{ij}^c$ shown here correspond to the right-hand panel of Figure 5. Values of estimates ${\widehat{\pi }}_c$ and associated standard errors are also shown for each class.
