Hi !

Would it be possible to have a reference for the method used to estimate LD from unphased GT in ld\_prune()?

Thanks a lot,

Hi @barioux,  
Have you already looked at the [method documentation](https://hail.is/docs/0.2/methods/genetics.html#hail.methods.ld_prune)? If so, can you be more specific about what is missing?  
Thanks!
