Biophysical parameters of symmetric and (significantly) asymmetric sister pairs.

Sister 1 is the sister with the greater pulling force in an asymmetric pair (i.e. ). The second and fourth columns report the medians of posterior medians for symmetric and asymmetric sisters respectively; the population interquantile range (IQR) is shown in brackets. The average parameter confidence per trajectory is shown in the third and fifth columns, specifically the median of Posterior Interquantile Ranges (PIR) for symmetric and asymmetric sisters, respectively. Based on Mann-Whitney and Kolmogorov-Smirnov tests, the asymmetric posterior distributions of , α, and L are significantly different from the symmetric posterior distributions, with effect sizes (percentage difference of the medians) of 15.9%, 34.3%, 9.5%, and 2.6%, respectively. Inference on asymmetric sisters is based on .
