How do you test for remaining autocorrelation in the Lag model?
My spatial diagnostics of OLS model showed clear indication of
autocorrelation on residuals, so I apllied the lag model to try to get rid
of this problem. However, regardless what I do to the model, The Likelihood
Ratio Test comes always up as significant. In the GeoDa Workbook, page 209,
it says "The (second) test is an alternative to the asymptotic significance
test on the spatial autoregressive coefficient, it is NOT a test on
remaining spatial autocorrelation."
So, how do we know whether or not the problem of autocorrelation was solved?
Vania Ceccato Ps. The test on remaining autocorrelation was available in
SpaceStat, why is it gone in GeoDa?
