Abstract: Dependence measure plays a fundamental role in statistical analysis, such as fMRI data analysis, variable selection, network analysis, genetical analysis, PPI network analysis. The aim of this paper is to provide a state of the art on the topic of dependence measure and to show their properties. We classified all these dependence measures into 3 classes:(1) Extension of correlation coefficient; (2) Dependence measures based on independent conditions; (3) Dependence measures in learning framework; As showed in our analysis, there is no such a dependence measure has the best performance over all kinds of functional types. However, according to the properties that a dependence measure should have combing with our results, CDC[4] is the best one. Furthermore, CDC2-ρ2 or CDC-|ρ|is proposed as a measure of non-linearity, which is better than MIC-ρ2, as showed in our analysis, where ρ is the Pearson correlation coefficient.

Key words: Dependence, CDC, Dependence measure, Non-linearity measurement
