In this article, I introduce a new command, xtdcce2, that fits a dynamic common-correlated effects model with heterogeneous coefficients in a panel with a large number of observations over cross-sectional units and time periods. The estimation procedure mainly follows Chudik and Pesaran (2015b, Journal of Econometrics 188: 393-420) but additionally supports the common correlated effects estimator (Pesaran, 2006, Econometrica 74: 967-1012), the mean group estimator (Pesaran and Smith, 1995, Journal of Econometrics 68: 79-113), and the pooled mean group estimator (Pesaran, Shin, and Smith, 1999, Journal of the American Statistical Association, 94: 621-634). xtdcce2 allows heterogeneous or homogeneous coefficients and supports instrumental-variable regressions and unbalanced panels. The cross-sectional dependence test is automatically calculated and presented in the estimation output. Small-sample time-series bias can be corrected by half-panel jackknife correction or recursive mean adjustment. I carry out a simulation to prove the estimator's consistency.
