makeDistancesAndWeights {ExPosition}

Makes distances and weights for MDS analyses (see epMDS).

Description

Makes distances and weights for MDS analyses (see epMDS).

Usage

makeDistancesAndWeights(DATA, method = "euclidean", masses = NULL)

Arguments

DATA

A data matrix to compute distances between row items.

method

which distance metric should be used. method matches dist; Two additional distances are avaialble: "correlation" and "chi2". For "chi2" see chi2Dist. Default is "euclidean".

masses

a diagonal matrix (or vector) that contains the masses (for the row items).

Value

D

Distance matrix for analysis

MW

a list item with masses and weights. Weights are not used in epMDS.
