This program consists of a group of segments for which the
output of one segment is the input of the next. It enables the
significance of linear, quadratic, and cubic trend surfaces to
be determined for each of a number of variables on the coor-
dinates of their distribution in two-dimensional space. The
significance of the various surfaces having been determined,
the fitted surface can be plotted by means of a contour map
on the teletype.
