Using the correct standard errors in comparing subpopulation survival rates in marked populations.
We give estimates of variances and covariances of survival rates for subgroups of a wild population surveyed by mark-recapture methods. These are used in forming test statistics to compare subgroup survival rates. We show that using correct standard errors based on the appropriate approximate sampling model and incorporating important covariances of observed frequencies avoids spurious significance of survival rate differences.
