Table 6 Descriptive statistics and correlation coefficients for randomly generated cover data sets (i) before and (ii) after the SACFOR encoding and numeric conversion. Both before and after data sets are transformed (log2) and converted to relative abundances. Values are based on 10 iterations of the simulation
