Please explain and help solve by referring to the information below.


In Fig. 6.e2a we are given the spatial arrangement of 7 data points together with the corresponding data values, as well as 1 point where an estimate is sough (denoted as "?"). The distances between the data and the estimation point are also shown in Fig. 6.e2b. Using the GID technique derive estimates at location "?" for p =1 and 5. Local data configuration Distance of each sample from point "?" 145.0 145.0 141.0 791 69 606 141.0 177 137 0_ 137.0 133.0 133.0 129 0 227 646 783 129 0_ 95 13.5 125.0_ 125.0_ 55.0 60.0 65.0 70.0 75.0 55.0 60.0 65.0 70.D 75.0 80.0 (a) (b) Figure 6.e2: (a) Data values and configuration.
