A robust Spearman correlation coefficient permutation test

Spearman Rank Correlation Coefficient

Spearman Permutation Distances and Shannon's Distinguishability

Spearman distance is a permutation distance which might prove useful for coding, e.g. for codes on permutations. It turns out, however, that the Spearman geometry of strings is rather unruly from the point of view of error correction and error detection, and special care has to be taken to discriminate between the two notions of codeword distance and codeword distinguishability. All of this str...

RoCoCo - An R Package Implementing a Robust Rank Correlation Coefficient and a Corresponding Test

This document is a user manual for the R package rococo. It is only meant as a gentle introduction into how to use the basic functions implemented in this package. Not all features of the R package are described in full detail. Such details can be obtained from the documentation enclosed in the R package. Further note the following: (1) this is not an introduction to robust rank correlation; (2...

Robust Image Registration Using Selective Correlation Coefficient

\Ve propose a new method for robust image registrat,ion called 'Selective Correlation Coefficient (SCC)' in order to search images under illconditioned illuminat,ion or partial occlusion. A correlation mask image is generated for selecting pixels of a image before matching. The mask image can be derived from a binary-coded increment sign image defined from any object image and the template imag...

Diabetic Erythrocytes Test by Correlation Coefficient

Even when a healthy individual is studied, his/her erythrocytes in capillaries continually change their shape in a synchronized erratic fashion. In this work, the problem of characterizing the cell behavior is studied from the perspective of bounded correlated random walk, based on the assumption that diffractometric data involves both deterministic and stochastic components. The photometric re...
