Generate multivariate Statistics for a cube
Description

History
Description
This application generates the correlation and covariance for a single cube which can be used
to evaluate the similarity and/or disimilarity between bands of a cube. Each band of the cube
is compared against every other band in the cube, generating a covariance matrix and a correlation
matrix, which are output to CUBE and/or FLATFILE.

Description
This output cube is a two band cube containing the correlation and covariance matrices. The dimensions of this cube will be NxNx2, where N is the number of bands in the input cube. The first band will contain the correlation matrix, and the second will contain the covariance matrix.
