Longitudinal data analysis <strong>for</strong> equi-spaced times<br />
When the number of time points n becomes at all large (5<br />
or more), it can be critical to conserve degrees of freedom<br />
used to represent covariation, and especially <strong>for</strong> mixed<br />
effect designs<br />
It can be reasonable to assume that covariances are<br />
substantial over only limited time lags<br />
Stationary and band-structured covariance structures are<br />
often used.
