Dear Statlist,
My research group is attempting to switch from doing Splines in Splus to doing Splines in Stata. I am using the GAM: Stata module for generalised additive models from the Boston College SSC archives. The program works well.
When using the Spline program in Splus, population density is shown by hash marks on the x-axis. I cannot find anything that will do this in Stata. The only way I have found to show the population density is by including the residuals on the graph, but this clutters the graph. Does anyone know of a better way to show the population density?
Thanks,
Ray
