Compute distances between all pairs of samples and plot distances in a cumulative histogram.
Compute Voronoi polygons and compute declustered basic statistics. An histogram of the Voronoi polygon areas are displayed at right.
Overlap a set of samples with a mesh of cells and compute average values of several variables within each cell. After, compute global declustered basic statistics.
Perform a trend analysis of a quantitative variable along X and Y directions.
