This function computes what are (approximately) chi-squared test statistics for independence of the genotypes at different points on the genome. This computation is done using the IBD probability data. Significant non-independence between IBD probabilities at distant points on the same chromosome, or points on different chromosomes, can indicate non-standard genetic inheritance or selective pressure.
A square matrix with rows and columns corresponding to genetic locations, and values corresponding to test statistics.
