Local Singularity

Fig. 11.37 Logarithmically (base 10) transformed KTB copper concentration versus local similarity
after k ¼ 100 iterations with regression line (singularity assumed to be error-free). Variance of loga-
rithmically transformed copper concentration value is 0.00823 (Source: Agterberg 2012b ,Fig.14)
