Kind regards, Carlo With panel data, we can model the heterogeneity and evaluate changes over time. I believe the reason is that in the great majority of instances, one has data for a small number of waves, and consequently does not have enough time points to estimate such models with an acceptable degree of precision, especially those with monthly components. Instead use specialized panel commands after xtset: I xtdescribe: extent to which panel is unbalanced I xtsum: separate within (over time) and between (over individuals) variation One rarely, if ever, sees ARIMA models being estimated with panel data. For example, I want the DGP (data generating process) is something like: Setting up panel data in Stata” refers to the process of organizing and preparing data for analysis when working with panel data in the statistical software Stata. 5617 I used fixed effect and time specific dummies to overcome the endogeneity problem.

We can use the title option to change the title of the plot and change the titles of x- and y-axes through xtitle and ytitle, respectively. Then data viewed as clustered on the individual unit. This means that when your science says that the model should be nonlinear in the parameters, as in the constant elasticity of substitution (CES) production function or in a growth curve for adoption of a new technology, you can now fit that model even when you have panel data. Specifying the tvd option causes xtfrontier to estimate the parameters of this model. That said, pooled OLS seldom outperforms -xtreg- when you deal with a panel dataset. By construction, the unobserved panel-level effects are correlated with the lagged dependent variables, making standard estimators inconsistent. New in Stata 18.
