Notes.

(a)

W (WISSH), W+C17 (WISSH + C17 sample);

(b)

Null-hypothesis probability;

(c)

Mean and standard deviation of the ρ accounting through simulations for errors in the two quantities (see text for details). This has been computed only for the relations with p ≲ 0.02;

(d)

90% percentile of the distribution of the p values obtained from the simulated random datasets (see text for details). This has been computed only for the relations with p ≲ 0.02;

(e)

Units of 10−3;

(f)

Generalised Spearman’s ρ computed with the survival analysis package ASURV v. 1.2;

(g)

Linear regression based on EM algorithm with normal distribution computed with the survival analysis package ASURV v. 1.2. The functional form for a Y − X relation is Y = α × X + β.
