st: spregsdmxt - where is it?

[Jennifer Day <jennieday@gmail.com>]

Hello out there!

I'd like to estimate an MLE spatial Durbin panel regression.  According to the Stata help files for spmstard <help spmstard>, there is a routine all written for this.  However, I can't find any help files or documentation on it.  Absolutely nothing pops up either, when I google "Stata spregsdmxt."  I've also tried <findit spregsdmxt> and <ssc install spregsdmxt> at the Stata command line.  Nothing!  I also tried searching for spregxt, in find it and ssc install, thinking this might be a parent program.  Still nothing!

How can I use spregsdmxt?  Here's the language that appears in the spmstard help files:
