... include partitional clustering and hierarchical clustering (Hartigan, 1975; Jain et al., 1999). A partitional method partitions the data objects into K (often specified a priori) groups according to some optimization criterion. The widely-used k-means algorithm is a classic example of partitional me ...

Human genetic clustering



Human genetic clustering analysis uses mathematical cluster analysis of the degree of similarity of genetic data between individuals and groups in order to infer population structures and assign individuals to groups. These groupings in turn often, but not always, correspond with the individuals' self-identified geographical ancestry. A similar analysis can be done using principal components analysis, which in earlier research was a popular method. Many studies in the past few years have continued using principal components analysis.
