Euclidean distance. Mahesh Kumar. Jewel Refran Follow. Download presentation. This criticism can be made against any statistical technique, but cluster analysis is generally considered more dependent on the measures used to characterize the objects than other multivariate techniques. With the development of Dendogram, the HCA so afford the researcher with a simple, yet comprehensive portrayal of clustering solutions. Euclidean Distance: based on the hypotenuse of a right triangle, connecting two points in two dimensional space. No Downloads. Creates a new variable indicating the Euclidean distances bet.

      Each cluster solution is a separate analysis, in contrast to the hierarchical techniques that generate all possible cluster solutions in a single analysis. Cluster analysis 1.
