Abstract
To genetically improve resilience, the autocorrelation between subsequent deviations from fitted curves of longitudinal data was proposed. Autocorrelation is related to the speed of recovery after a disturbance: a high autocorrelation means slow recovery, while a low autocorrelation means fast recovery. It is known that estimated autocorrelations are biased, while the genetic properties of the autocorrelation are largely unknown. The aims of this research were to investigate the bias and the heritability of the autocorrelation. Deterministic expressions were derived and evaluated with Monte Carlo simulation. The estimated autocorrelation was 0.2-0.3 lower than the true value when the number of records was 10. The heritability was between 0.05 and 0.10 in most situations. It is recommended to have at least 50 records per animal. This shows good opportunities for genetic improvement. This study is a first step towards better understanding of the mathematical and genetic properties of the autocorrelation.
