Fitsum Abadi, Olivier Gimenez, Raphaël Arlettaz, and Michael Schaub. 2010. An assessment of integrated population models: bias, accuracy, and violation of the assumption of independence. Ecology 91:7–14.

Appendix B. Detailed summary of the relative bias, standard error, and mean squared error of the integrated and conventional analyses.

TABLE B1. Relative bias (rel. bias), precision (std. error: standard error) and accuracy (MSE: mean squared error) of the parameter estimates obtained with integrated and separate analyses (CR: capture–recapture, RS: reproductive success, PS: population survey) for different sample sizes under independent and dependent scenarios.
