Table 5 PERMANOVA comparison of randomly generated count data sets (i) before and (ii) after the SACFOR encoding and numeric conversion. Both before and after data sets are transformed (log10) before analysis and converted to: (i) relative abundances; and (ii) rank of abundances. Values are based on 10 iterations of the simulation. Number of permutations: 999
