proc spatialreg / defining weight matrix

Cruise — Sat, 11 Apr 2020 00:06:59 GMT

Hi Folks:

I'm trying to define the spatial matrix for a South Korea in proc spatialreg using the macro suggested in the SUGI paper below.

The macro requires a map data.

Would South Korea map in Mapsgfk library work for this purpose? I just noticed that lat/long variables were labelled as unprojected in the proc contents.

Any hints are appreciated.

For most things involving SAS map data sets I would tend to use the X Y coordinates.

Hey, you're right. There are X Y coordinates in the data set in addition to lat/long. Also, I realized that the definition of variables of macro includes y and x axis variables as well.
• lat = specifies the latitude or y axis variable.
• long = specifies the longitude or x axis variable.
Thanks ballardw. I greatly appreciate it.
