Keywords: non-parametric regression, thin plate splines.
Data were collected from a mine in Cobar, NSW, Australia. At each of 38 sampling points, several measurements were taken, one of which is the 'true-width' of an ore-bearing rock layer. Also given are the co-ordinates t1 and t2 of of the data sites. Green and Silverman (1994) use this data set to illustrate thin-plate splines for fitting a smooth surface.
