Hello everyone,

I would like to know whether it is possible to use the spatial autoregressive model to impute missing values in aggregate data? If the OLS model is replaced with SAR model in regression imputation, would it lead to better estimates for missing values in a spatial data? Any opinion/ suggestion is appreciated.

Please see the article referenced in the help page for spatialreg::predict.sarlm():

Michel Goulard, Thibault Laurent & Christine Thomas-Agnan, 2017 About predictions in spatial autoregressive models: optimal and almost optimal strategies, Spatial Economic Analysis Volume 12, Issue 2-3, 304-325

The differences in the spatial error model would be through any differences in covariate coefficient values, but if the differences are large, the Hausman test for misspecification would fail. Your post nudged me to raise an issue on spatialreg about SLX prediction, which very likely also makes sense, and to check predictions where Durbin=TRUE more generally.

Thanks in advance.
