Centroid:
The centroid of several continuous variables is the vector of means of those variables.
The concept of centroid plays the same role, for example, in multiple analysis of variance (MANOVA) as the mean plays in analysis of variance (ANOVA) .
This course will teach you how to use various cluster analysis methods to identify possible clusters in multivariate data. Methods discussed include hierarchical clustering, k-means clustering, two-step clustering, and normal mixture models for continuous variables.
