Panel data consist of repeated observations over time on the same set of cross-sectional units. These units can be individuals, firms, schools, cities, or any collection of units one can follow over time. Special econometric methods have been developed to recognize and exploit the rich information available in panel data sets.Repeated measures anova assumes that the within-subject covariance structure has compound symmetry. There is a single variance (σ 2) for all 3 of the time points and there is a single covariance (σ 1 ) for each of the pairs of trials. This is illustrated below. Stata calls this covariance structure exchangeable.5.2k members in the stata community. Stata news, code tips and tricks, questions, and discussion!

In Stata , xtset is used when you want to use the xt suite of commands and the purpose of xtset is to tell Stata what your panel ID and time variables are. Note that xtset is to be used in conjunction with a host of xt models, including xtreg, xtlogit, and xtpoisson but not xtmelogit.There are repeated times within panels, which is why xtset with identifier and time variables fails. If you ignore the panel identifier and try tsset then you have the same problem of repeated times, but multiplied. At most, but very possibly quite helpfully, you can use xtset with a panel identifier alone. That seems to match the set-up here.However, when using "xtset" (a first needed Stata command before using "xtreg" or any of the other -xt- models) Stata indicates that repeated time values are not allowed, a feature of my data.
