Iterated GLS with autocorrelation does not produce the maximum likehood estimates, so we cannot use the likelihood-ratio test procedure, as with heteroskedasticity. However, Wooldridge (2002, 282–283) derives a simple test for autocorrelation in panel-data models. Drukker (2003) provides simulation results …

This talk: overview of panel data methods and xt commands for Stata 10 most commonly used by microeconometricians. Three specializations to general panel methods: 1 Short panel: data on many individual units and few time periods. Then data viewed as clustered on the individual unit. Many panel methods also apply to clustered data such as I don't know what an ARDL(xxxx) model implies exactly, but I'd like to point out that gen x = x [_n-1] is not a good way to generate lagged variables. Rather, I suggest you use L.x in the regression command and let Stata do its thing, or generate it yourself as L_x = L.x.The problem with the _n-1 method is that for the second panel, this will use the last value of the …26 Jul 2018, 22:51. Lyuwork: - Stata can perform panel data regression on an unbalanced panel, too.

Data panel sering disebut juga sebagai data longitudinal. Data ini melihat observasi beberapa variabel cross section dan memperhatikan data deret waktu yang digunakan (time series). Jadi bila diterjemahkan dengan bahasa yang lebih mudah, data panel adalah data yang merupakan gabungan dari cross section dan time series.

Panel Data Estimation in Stata. This document, a companion to the Panel Data series of lecture notes, provides a brief description of how to implement panel data models in Stata. We will load the Tobias and Koop but this time will use the entire dataset since we are now ready to exploit the panel nature of the full dataset.

Stata 14 now provides panel-data parametric survival models. Examples of survival outcomes in panel data are the number of years until a new recession occurs for a group of countries that belong to different regions, or weeks unemployed for individuals who might experience multiple unemployment episodes.
