Introduction Health-care researchers use survey data to evaluate 1. Stata has suite of tools for dynamic panel-data analysis: xtabond implements the Arellano and Bond estimator, which uses moment conditions in which lags of the dependent variable and first differences of the exogenous variables are instruments for the first-differenced equation. Sometimes the observations are from a single case, but more often they are aggregate scores from many cases. Since time-series are ordered in time their position relative to the other observations must be maintained. These are documented in the panel data volume of the Stata manual set, or you can use the -help- command for xtreg, xtgee, xtgls, xtivreg, xtivreg2, xtmixed, xtregar or areg.
