Allele-specific likelihood-based test for the inbreeding among samples
INFO=<ID=AS_InbreedingCoeff,Number=A,Type=Float,Description="allele specific heterozygosity as estimated from the genotype likelihoods per-sample when compared against the Hardy-Weinberg expectation; relate to inbreeding coefficient">
This annotation estimates whether there is evidence of inbreeding in a population. The higher the score, the higher the chance that there is inbreeding.
The calculation is a continuous generalization of the Hardy-Weinberg test for disequilibrium that works well with limited coverage per sample. The output is the F statistic from running the HW test for disequilibrium with PL values. See the method document on statistical tests for a more detailed explanation of this statistical test.
