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
