List, I'm having some trouble importing a Geoda generated distance band weight matrix into R for use with the spdep regression tools. The "read.gwt2nb" function does not work, and even when I try to import a manually created version of the matrix, I cannot seem to get it into the right format to avoid frame errors when attempting to estimate lag/error models. Once I import the data in properly, I intend to perform a test of the common factor hypothesis, which is unavailable in Geoda.
Up to this point, I've tried to use "mat2listw", but the program returns a faulty "matrix not standardized" warning, and then produces the frame errors after regression commands. So, I have two questions: 1) Is there a pre-packaged "read.gwt2..." function that imports distance based weight matrices into R for use with spdep? 2) Failing that, how can I import a distance band weight matrix into R (for use with spdep) while avoiding frame errors? Thanks in advance for your help! -Mike Adjemian _______________________________________________ R-sig-Geo mailing list [email protected] https://stat.ethz.ch/mailman/listinfo/r-sig-geo
