Using intraclass correlation coefficient and Bartlett test statistic to identify soil layer boundaries / Lim Jit Kheng … [et al.]

In this study, the performance of two statistical methods, namely intraclass correlation coefficient (RI) and Bartlett test statistic in conjunction with various suggested window widths are investigated to identify soil layer boundaries. The study is done using three fairly different CPT soundings o...
