Ashley Arnio <> has some questions about the user-written
-spivreg- command:

The two models are not equivalent.  To learn more about the various
spatial-autoregressive models with endogeneous variables Ashley should read
sections 2 and 6.4 of the working paper 'A command for estimating
spatial-autoregressive models with spatial-autoregressive disturbances and
additional endogenous variables' available at
