If you just specify panel and year variables, Stata expects unit spacing, so lag 1 with yearly data means "the previous year". Asking for a lag 1 variable is legal, but all values are missing. xtset ID Year gen lag1 = L1.Y. If you specify delta (5) then a lag 1 variable is missing in all but two observations. xtset ID Year, delta (5) gen lag5 ...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.

In my understanding, a pooled OLS regression in STATA is provided through the command reg or regress (which is completely the same). However, it does not seem that this approach takes the actual panel structure into account. Nevertheless, the researchers of the mentioned paper utilize exactly this term “pooled (panel) regressions” (p.24).Nov 16, 2022 · The multinomial logit (MNL) model is a popular method for modeling categorical outcomes that have no natural ordering—outcomes such as occupation, political party, or restaurant choice. In longitudinal/panel data, we observe a sequence of outcomes over time. Say that we observe restaurant choices made by individuals each week.
