Table 1. Correlation analyses of raw and generalised-differenced (detrended) data of genus-level Cambrian–Silurian PBDB diversity. The relationship between the (total and the boundary-crossing, BC) observed and the sampled-in-bin (SIB) and the occurrence richness as a measure of sampling effort is tested. Both variables are analyzed per time unit. The parametric Pearson (r), and non-parametric Spearman (rs) and Kendall (t) correlation tests were implemented. The corresponding correlation coefficients together with their associated probability values of nocorrelation (p) are shown. * Significant values (p < 0.01). ** Highly significant values (p < 0.001).
