Nick Cox is right: I wrote this program 10 years ago when I started my
Ph.D. program... few people on this list would remember how to program
in Stata 7 :). You should try to figure out how the paper you
mentioned (consider providing the full reference here on the list!)
defines the knots, and then see if you can get something similar from
my -thinplate generate-. Then you can feed these knots into a regular
-regress-, get the predicted values, and plot them using Stata 12
-twoway contour- (which I inquired about at a Stata User Group Meeting
roughly at the same time I wrote -thinplate-). That's the best advice
I can give at the moment.
