Abstract Linearly independent, orthogonal, and uncorrelated are three terms used to indicate lack of relationship between variables. This short didactic article compares these three terms in both an algebraic and a geometric framework. An example is used to illustrate the differences.

A lot of chemometrics is expressed in terms of vectors in multidimensional space. In this article, we will look at various properties of vectors, namely, linear independence, orthogonality, andExpand

Thirteen ways to look at the correlation coefficient
Abstract In 1885, Sir Francis Galton first defined the term “regression” and completed the theory of bivariate correlation. A decade later, Karl Pearson developed the index that we still use toExpand

Uncorrelated Multilinear Discriminant Analysis With Regularization and Aggregation for Tensor Object Recognition
TLDR
The UMLDA aims to extract uncorrelated discriminative features directly from tensorial data through solving a tensor-to-vector projection, and an adaptive regularization procedure is incorporated to enhance the performance in the small sample size (SSS) scenario. Expand
Significance Testing of Congruence Coefficients: A Good Idea?
Tucker's congruence coefficient is often used to compare the equality of latent structures on a given test for different subgroups. Initial use of the index was subjective; given the same congruenceExpand
