Three instances of sample correlation. (a): course of the unitary delay autocorrelation $\rho$ of a truncated sample of U with the truncating threshold $\tau$. (b) Course of $\rho$ of very large forcedly dependent samples of U with r as in (4). (c) ECDF of 100 forcedly correlated samples with $r=0.5$ (blue curves) and 100 biased samples with $d=0.6$. (green curves).
