Some New Copula Based Distribution-free Tests of Independence among Several Random Variables
Angshuman Roy, Anil Ghosh, Alok Goswami +1
Over the last couple of decades, several copula based methods have been proposed in the literature to test for the independence among several random variables. But these existing t…
RelDenClu: A Relative Density based Biclustering Method for identifying non-linear feature relations
Namita Jain, Susmita Ghosh, C. A. Murthy
The existing biclustering algorithms for finding feature relation based biclusters often depend on assumptions like monotonicity or linearity. Though a few algorithms overcome this…
A Nonparametric Ensemble Binary Classifier and its Statistical Properties
Tanujit Chakraborty, Ashis Kumar Chakraborty, C. A. Murthy
In this work, we propose an ensemble of classification trees (CT) and artificial neural networks (ANN). Several statistical properties including universal consistency and upper bou…
Multivariate Dependency Measure based on Copula and Gaussian Kernel
Angshuman Roy, Alok Goswami, C. A. Murthy
We propose a new multivariate dependency measure. It is obtained by considering a Gaussian kernel based distance between the copula transform of the given d-dimensional distributio…
Sparsity Measure of a Network Graph: Gini Index
Swati Goswami, C. A. Murthy, Asit K. Das
This article examines the application of a popular measure of sparsity, Gini Index, on network graphs. A wide variety of network graphs happen to be sparse. But the index with whic…
A new estimate of mutual information based measure of dependence between two variables: properties and fast implementation
Namita Jain, C. A. Murthy
This article proposes a new method to estimate an existing mutual information based dependence measure using histogram density estimates. Finding a suitable bin length for histogra…
