st: New command available on SSC

[Ed Blackburne <blackburne@shsu.edu>]

Statalisters,

Thanks to Kit Baum, -xtpmg-, a new package by Ed Blackburne and
Mark Frank, is available from the SSC Archive.

-xtpmg- is useful for estimating nonstationary heterogeneous panels 
in which the number of groups and number of time-series  
observations are both large. -xtpmg- provides three alternative estimators: a 
traditional fixed-effects estimator, the mean-group estimator of 
Pesaran and Smith (Estimating long-run  relationships from dynamic 
heterogeneous panels, Journal of Econometrics 68:  79-113), and the 
pooled mean-group estimator of Pesaran, Shin, and Smith (Estimating 
long-run relationships in dynamic heterogeneous panels, DAE Working
Papers Amalgamated Series 9721; Pooled mean group estimation of dynamic
heterogeneous panels, Journal of the American Statistical Association 94: 
621-634).  This routine is described in Stata Journal, 2007, 7:2, 197-208

To install the package from within Stata, type

. ssc install xtpmg

-xtpmg- is compatible with Stata 9 or newer.

Please direct any comments regarding -xtpmg- to me.
