Hello

I´m trying calculate a spatial durbin model, however i can´t generate Spatially Weighted Regressors.
when i´m using the following code it gives error.

code:
spgenerate W_x1=W*x1

error:
weighting matrix W not found
r(111)

which is strange cause I already had estimate a Spatial Lag an error model before.


thankfully
