Spatial error model estimation
Greetings to the list,
I was trying to estimate spatial error model in R, somehow I got the
message below. Would you please help me with it? Many thanks in
advance.
Error in solve.default(asyvar, tol = tol.solve) :
system is computationally singular: reciprocal condition number = 5.6964e-18

Error in spdep: system is computationally singular
...dr,2)+poly(mdr,3))
final.glm1<-step.gam(glm1,glm.scope,direction="back")
**I want to estimate the spatial simultaneous autoregressive error model**
res20<-errorsarlm(finalglm1, listw=nb20.w, zero.policy=TRUE)
But here I receive the following error message:
Error in solve.default(asyvar, tol = tol.solve) :
system is computationally singular: reciprocal condition number = 2.8713e-12
What is happening? What does this message mean?
Thanks a lot,
Alberto
