Additionally, the DWT-based MRA can only separate the variations in soil properties at some pre-selected scale intervals or scales with two-fold increments (also known as dyadic scales) (Percival and Walden, 2000). Though a sample size of 2n (n = any integer) can make the analysis faster, the pre-selected scale intervals may not represent a physically meaningful scale analysis (Biswas and Si, 2011 and Lau and Weng, 1995). However, soil properties can vary at any scale and not at some pre-selected scale intervals.
