Before SAS/ETS 14.2, no intended process for estimating spatial regressions exists. I proposed a series of three macros to do that. The macros were presented at the 22nd-day conference for Quebec City's SAS users.
You can get my presentation [in French] or on SAS users website. I provided three macros: the first for Moran and Geary tests, the second for spatial regressions estimation, and the last for specification tests. Get the macros files below:

Here is an example with simulated data on Africa’s countries.
