The documentation for the survConcordance() function in the survival package defines concordance as “the probability of agreement for any two randomly chosen observations, where in this case agreement means that the observation with the shorter survival time of the two also has the larger risk score. The predictor (or risk score) will often be the result of a Cox model or other regression” and notes that: “For.

able, survival rates, particularly of long-lived, free-ranging animals, can be very challenging to estimate (Newton et al. 2016). However, over recent decades, advances in tracking and modelling techniques have greatly facilitated the estimation of survival rates, with avian research being particu-larly active on this front (e.g. MARK: White &
