Dear community, I am trying to run a spatial panel random effects SEM model using splm package on a balanced spatial panel of N = 2472 and T = 4, and weights are based on k = 6 nearest neighbors. I encounter this error, which I can't find anything about in the documentation or online.
spml(formula = mx.standard ~ I.score, data = analysis.subset, listw = listw.wgts, effect = "individual", model = "random", lag = FALSE, spatial.error = "b", index = c("Group", "Year")) Error in .C64("aplsb1", SIGNATURE = c(SS$signature, SS$signature, "double", : NAs in argument 7 and 'NAOK = FALSE' (dotCall64) Unlike the same specification but with fixed effects (with model = "within" argument), the one above takes a long while to run until it crashes. As far as I can tell, there are no memory issues. An alternative spatial random effects using spgm() command runs OK, as do non-spatial fixed and random effects models using plm(). For the one above I could use spgm(), but I would prefer to keep all my models in the maximum likelihood estimation for consistency. Any clarifications as to the nature of the error are welcome. Thank you. Denys Dukhovnov _______________________________________________ R-sig-Geo mailing list R-sig-Geo@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-geo
