Applications of Robust Methods in Spatial Analysis

Figure 5

In subplots (a) and (b), the -axis and -axis indicate the position of a location in the east-west and north-south directions respectively. (a) 20 optimal locations; (b) 30 optimal locations; (c) losses of 150 runs for 20 optimal locations; and (d) losses of 150 runs for 30 optimal locations for the coal-ash study. In subplot (c) and (d), the -axis and -axis represent minimum loss and run, respectively.
