Maybe "e" has the wrong class. Probably it is a matrix. Try listw = mat2listw(e)

But I am new to R, and I have indeed spent several hours online trying to avoid spamming this forum with basic questions. I am still not able to find out what's wrong. I attach my code! I nead to estimate a spatial panel model. In doing so, I have installed and loaded the "splm package". > b<- > read.dta13('C:/Users/Peter/Documents/R/win-library/3.2/ENHR/tillvaxtte > st2.dta') > mydata1=read.table('C:/Users/Peter/Documents/R/win-library/3.2/ENHR/av > stand6.txt', header=FALSE) > > e=matrix(mydata, nrow=286, ncol=286) > tillvaxt<-pdata.frame(b) > > fm<-dlnypc~Totinfly+totutfly > > fespaterr <- spml(fm, data = tillvaxt,listw =e, + model="within", spatial.error="b", Hess = FALSE) Error in listw2mat(x) : non-positive number of entities The error message is found in the last line. I am checking my "weighting matrix" and according to my understanding, the matrix fulfills the requirement (i.e. the diagonal elements are zero, whereas remaining elements are positive). It is a symmetric 286X286 matrix. Obviuosly, there is something wrong with my e-matrix, but I can't figure out how. There are in fact no negative elements in the matrix. Thank you in advance!
