motivated by some examples shown here earlier by Reynaldo we have
updated the PMG contributed function package to version number 1.0. (It
does pooled mean group estimation for large-T panel datasets.) The main
computational news is that the default initial values used for the
estimation algorithm should be better now for most cases. (However,
coauthor Jack also found an example where the old initialization is
actually better, so as the user you get an --expert-- choice and can try
both if needed.)
For scripting there's also a slightly simpler interface function which
is just called PMG(). See the included pdf help file of the package.
As always, you can download and install the new package version directly
from within gretl.
