My panel variable is a person id and my time series variable is the year. You can also take snapshots of only specific data streams or indices in the cluster. If you end up in a situation where you need to restore a snapshot of a data stream or index that is incompatible with the version of the cluster you are currently running, you can restore it on the latest compatible version and use reindex-from-remote to rebuild the data stream or index on the current version. to multilevel modeling. Using Stata’s postestimation commands to calculate a likelihood ratio test As you have seen, it is easy enough to calculate a likelihood ratio test “by hand.” However, you can also use Stata to store the estimates and run the test for you. in your case counties. One-stage cluster sampling in Stata. Instrumental variables methods can provide a workable solution to many problems in economic research, but also bring additional challenges of bias and precision.
