heteroskedasticity corrections for lagsarlm() in spdep
I tested the procedure from Marco and it worked fine under the recent spdep update (05-40). But are there any heteroskedastic corrections for the other spatial models (Spatial lag, SAC or Spatial Durbin) estimated with ML-estimations (lagsarlm, errorsarlm, sacsarlm)? I know that there is the sphet package (use sphet_1.1-0), but in this are as far as I see only GMM procedures included. I am grateful for any suggestions --- Christian A.
