Correlations (upper triangle), variances (diagonal; divided by 100) and average differences (lower triangle; row estimator minus column estimator) between the different estimators.
*f is the genealogical coancestry calculated by the tabular method; for the other estimators, the corresponding formula in the text is indicated in parenthesis
