    Euclidean distance comparison weighted by correlation

    Hello, I want to calculate the Euclidean distance between two objects across a set of n variables. For those n variables I have generated a correlation matrix. From that correlation matrix I would like to produce a weight vector that I can apply before calculating the distance, so that the...

    Measure of overlap between two sets of ratings (Mahalanobis?)

    Hi all, I would like to compute a measure of overlap between two sets of ratings made by the same individual. To illustrate, let’s assume the following: A sample of individuals (N = 20) are asked to rate their own personality on nine different dimensions (e.g., emotional stability...

    Distance measures in cluster analysis

    Hi, I conducted a k-means cluster analysis, which included each person's Euclidean distance from the centroid of his/her assigned cluster. Is there a way to calculate each person's distance from the centroid of a DIFFERENT cluster than his/her assigned cluster? In other words, if a person...

    PERMANOVA - choice of distance measure

    Hi, I want to run a (PRIMER based) PERMANOVA analysis on my univariate data (output var.= weight of organisms, and 3 factors = 2 fixed, 1 random) and I'm wondering which distance measure (Bray-Curtis or Euclidean distance) to use to create the resemblance matrix. In most literature that I...
