Ahat


Using the simulated data from the family pedigrees in the Crossett et al arXiv paper, five families were randomly selected, and 10 individuals from the 15 related individuals were randomly selected independently in each family.  The $\hat{A}$ matrix was then calculated via the GCTA software of Yang et al.  In the resulting 50 x 50 relationship matrix, element $\hat{A}_{ij}$ represents the estimated kinship coefficient between individuals $i$ and $j$.


Treelets provides a novel construction of multi-scale bases that extends
wavelets to non-smooth signals. It returns a multi-scale orthonormal
basis, where the final computed basis functions are supported
on nested clusters in a hierarchical tree.  Both the tree and
the basis, which are constructed simultaneously, reflect the
internal structure of the data.
