combineRank

Description

A search algorithm which creates a ranked table of the greatest combined sum from each vector-elements in a list.

Usage

combineRank(dlist, loghdval = Inf, alpha = 0.99, maxsearch = 1000)

Arguments

dlist	A list with vector elements of decreased sorted values.
loghdval	An optional value used to stop the search together with alpha.
alpha	An optional value used to stop the search together with loghdval.
maxsearch	The size of the ranked deconvolved profile table will not exceed this number (used to avoid endless search).

Details

Helpfunction used in earlier version of deconvolution to obtain a global ranking of full profiles (across all markers) The procedure takes a list with vector elements of decreased sorted values and creates a ranked table of the most probable summed values (sum) from each vector-elements in the list.

The search is stopped when SUM(exp(sum-loghdval))>alpha or when the size of the ranked table is equal maxsearch

The search algorithm iterately compares a set new paths (by considering one step down in the ranked list for each list-elements). The information of earlier visited paths are stored with corresponing total sum. For the considered set of paths, the next iterative optimal path is the one with largest total sum.

Value

ret A list(rankG,pG) where rankG is the ranked genotypes with corresponding probabilities in pG.
