A New Procedure of Clustering Based on Multivariate Outlier Detection

... Hodge, 2004). Clustering is a popular technique used to group similar data points or objects in groups or clusters (Jain and Dubes, 1988). Clustering is an important tool for outlier analysis. Several clustering-based outlier detection techniques have been developed. Most of these techniques rely on ...

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.
