Distance cannot be negative. There are a few common measures of distance that the algorithm uses for the clustering problem. EUCLIDEAN DISTANCE. It is a default distance used by the algorithm. It is best explained as the distance between two points.
linked (with recombination fraction = θ) or that they are not linked (recombination fraction = 0.5). The ratio of these two likelihoods gives the odds of linkage, that is, how more likely the pedigree is under a model of linkage when compared to a model assum-ing no linkage. The logarithm of the odds is called the LOD score (Morton, 1955), [1] Nettetwith multiple individuals/loci (see next) , and extending them b eyond their current limits is the ongoing outstanding problem.
