Implementation of the 'ihs' version of iHS #4

Open szpiech opened 10 years ago

szpiech commented 10 years ago

As noted in the Sabeti et al. (2007) Supplemental Information, the program 'ihs' computes an undocumented modified iHS statistic. At moderate to large sample sizes (>50 haplotypes), 'ihs' and selscan are highly correlated (r > 0.99), but at very low sample sizes (~10 haplotypes) the two diverge somewhat.

I plan to add an option to compute the 'ihs' version of iHS.

Is there still a plan to add this in to selscan?

Yes, but it is currently relatively low priority.
