[edit] Proximity measures
The first program creates three proximity matrices: physical distance, language phylogeny, and cultural complexity. Cultural complexity is a Euclidean distance measure based on 10 SCCS variables, and one could easily rewrite the program a bit to make other proximity measures based on SCCS variables--I've tried things like subsistence and ecology. http://www.mtsu.edu/~eaeff/downloads/mkwmat.sas
The 186x186 language similarity matrix can be downloaded from http://intersci.ss.uci.edu/wiki/drw/AnthonEff/wmlang02112006.xls and earlier codes from http://intersci.ss.uci.edu/wiki/drw/AnthonEff/wmlngp.xls and http://intersci.ss.uci.edu/wiki/drw/AnthonEff/wmlngs.xls
[edit] Regression residuals
The second program tests regression residuals for autocorrelation, using the three weight matrices. IML is used to calculate the Moran statistic and its z value. I enter the IML code directly in the program, rather than calling it from a module--I think that makes it a bit easier to understand the program, though it is still pretty complicated. http://www.mtsu.edu/~eaeff/downloads/ac_resid.sas
[edit] Tests of SCCS variables for autocorrelation
The third program tests a set of SCCS variables for autocorrelation, using the three weight matrices. http://www.mtsu.edu/~eaeff/downloads/ac_variab.sas
[edit] The SAS dataset
I also include the SAS data set as it was when I last worked with the SCCS (probably two years ago). http://www.mtsu.edu/~eaeff/downloads/mrg.sas7bdat
I run SAS on a UNIX mainframe. By changing the path in the libname statement, you should be able to run these programs on any machine, but I haven't tried.
