CollapsABEL: Generalized CDH (GCDH) Analysis

Implements a generalized version of the CDH test (<DOI:10.1371/journal.pone.0028145> and <DOI:10.1186/s12859-016-1006-9>) for detecting compound heterozygosity on a genome-wide level, due to usage of generalized linear models it allows flexible analysis of binary and continuous traits with covariates.

Install the latest version of this package by entering the following in R:
