SEQUENCE LD/SEQUENCE LDHOT

Record added by Jurg Ott (the original Rockefeller list)

Description

The program sequenceLD analyzes sequence data. It obtains an approximation to the likelihood of a summary of the data (as such it can be thought of as a marginal likelihood approach). It does not use all the information in the data, but computationally it can be substantially more efficient than the full-likelihood methods (and hence able to analyze larger data sets). The program sequenceLDhot is a method for detecting recombination hotspots from population genetic data. It takes as input phased (i.e. haplotype) data, together with an estimate of the background recombination rate within the region (this is allowed to vary across the region). Then sequenceLDhot considers a grid of putative hotspot positions, and for each putative hotspot calculates a likelihood ratio statistics for the presence of a hotspot.
