st: Re: adoupdate

[Kit Baum <baum@bc.edu>]

The problem is that there are two versions of kpss that findit can  
find: the earlier version available from STB-58 and the more recent  
version available from SSC. adoupdate looks at where you originally  
got a package and examines that location's revision date to determine  
whether you have the latest version. Since you originally installed  
the routine from STB-58, that is where it locates the item. There is  
no way for Stata to understand that some of the _components_ of  
STB-58/sts15.1 are identical to those of the SSC kpss package. In  
that case, doing "ssc install kpss,replace" will bring you the new  
code and "remember" that you installed kpss.pkg from SSC. It will  
also still "remember" the STB-58 install, but that will do no harm.

The problem here is that STB/SJ packages are only updated by a  
Software Update, and that happens no more frequently than three  
months. Updates to any program published in STB/SJ thus often appear  
in SSC. Programs under frequent revision -- e.g. ivreg2 -- almost  
always have their most recent version on SSC. In that case, you  
should not install the STB/SJ version, but rather the SSC version.  
findit (or ssc describe) should report a later date for the SSC  
version. Software Updates for kpss, gphudak, roblpr and modlpr should  
appear in a forthcoming issue of the SJ.
