Panel data in stata
Using tsappend with panel data tsappend’s actions on panel data are similar to its action on time-series data, except that tsappend performs those actions on each time series within the panels. To work within panels, a panel variable must have been specified with tsset or xtset. It does not matter which command you use; the two are equivalent.This command creates a new variable newid that is 1 for the first observation for each individual and missing otherwise. _n is the Stata way of referring to the observation number; in a 10-observation dataset, _n takes on the values 1, 2, ..., 10. When _n is combined with by, however, _n is the observation number within by-group, in this case ...

The first is implemented by xttest0 in Stata (and in R in plmtest of package plm). The second in Stata by hettest (and in R in bptest of package lmtest) and - I believe - cannot readily be applied to panel models. The 2nd webpage seems to confuse both tests/use cases.In STATA, before one can run a panel regression, one needs to first declare that the dataset is a panel dataset.This is done by the following command: xtset id time. The command xtset is used to declare the panel structure with 'id' being the cross-sectional identifying variable (e.g., the variable that identifies the 51 U.S. states as 1,2,...,51), and 'time' being the time-series identifying ... xtreg is the command for panel model regression. ln_dvar is the natural logged continuous dependent variable. i.year is a indicator (dummy) variable for year, there are 8 years of data. ivar is ...1. Here is an example on how you create a dummy in a panel data and then collapse those dummy to the parent unit-of-observation making the dummy 1 if the parent unit-of-observation was 1 in any time period. Then merge the parent unit-of-observation level data back to the panel data. * Example generated by -dataex-.
