Calculate Moment Statistics

On Geostatistical analysis option of Analyze option of Main Program Menu.  This will produce results for all open DEMs.

For all open DEMs, or select a single DEM.

Moments of elevation, slope, or the two curvatures.

Graphs (histograms). 

Histograms can do the raw numerical count, or standardized so that is it easier to compare DEMs with different spacing and absolute number of points.
