QSAR Study of Skin Sensitization Using Local Lymph Node Assay Data (2008)
Adam Fedorowicz, Lingyi Zheng, Harshinder Singh, Eugene Demchuk
Abstract: Allergic Contact Dermatitis (ACD) is a common work-related skin disease that often develops as a result of repetitive skin exposures to a sensitizing chemical agent. A variety of...
Philip J. Bol, Harshinder Singh, Bojan Cukic
Abstract—The comparison of partition and random sampling methods for software testing has received considerable attention in the literature. A standard criterion for comparisons between random and...
Performance Analysis of Iris Based Identification System at the Matching (2005)
Natalia A. Schmid, Manasi Ketkar, Harshinder Singh, Bojan Cukic
Practical iris-based identification systems are easily accessible for data collection at the matching score level. In a typical setting, a video camera is used to collect a single frontal view image...
The stochastic precedence ordering with applications in sampling and testing (2004)
Boland, Philip J., Singh, Harshinder, Cukic, Bojan
Stratified and simple random sampling (or testing) are two common methods used to investigate the number or proportion of items in a population with a particular attribute. Although it is known that...
Mishra, Neeraj, Iyer, Srikanth K, Singh, Harshinder
We compare the performance of restricted and unrestricted maximum likelihood estimators of means ${\mu}_1$ and ${\mu}_2$ , and common variance ${\sigma}^2$, of two normal populations under LINEX...

Robust prediction of fault-proneness by random forests (2004)
Lan Guo, Yan Ma, Bojan Cukic, Harshinder Singh
Accurate prediction of fault prone modules (a module is equivalent to a C function or a C++ method) in software development process enables effective detection and identification of defects. Such...
Predicting Fault Prone Modules by the Dempster-Shafer Belief Networks (2003)
Lan Guo, Bojan Cukic, Harshinder Singh
This paper describes a novel methodology for predicting fault prone modules. The methodology is based on Dempster-Shafer (D-S) belief networks. Our approach consists of three steps: First, building...
Stochastic orders in partition and random testing of software (2002)
Boland, Philip J., Singh, Harshinder, Cukic, Bojan
Testing in order to produce software of high reliability is an area of major concern in software engineering. In an effort to find efficient methods of testing, the comparison of partition and random...
Probabilistic model for two dependent circular variables (2002)
Singh, Harshinder, Hnizdo, Vladimir, Demchuk, Eugene
Motivated by problems in molecular biology and molecular physics, we propose a five‐parameter torus analogue of the bivariate normal distribution for modelling the distribution of two circular...
Fisher Information in Weighted Distributions (1998)
Satish Iyengar, Satish Iyengar, Paul Kvam, Harshinder Singh
Standard inference procedures assume a random sample from a population with density f # (x) for estimating the parameter #. However, there are many applications in which the available data are a...
Probabilistic model for two dependent circular variables
Motivated by problems in molecular biology and molecular physics, we propose a five-parameter torus analogue of the bivariate normal distribution for modelling the distribution of two circular random...

Stochastic comparisons of Poisson and binomial random variables with their mixtures
Misra, Neeraj, Singh, Harshinder, James Harner, E.
Motivated by an ecological sampling problem, we compare a Poisson distribution having a fixed mean with a Poisson distribution having a random mean, which has an arbitrary continuous (or discrete)...
Order restricted estimators: some bias results
Sampson, Allan R., Singh, Harshinder, Whitaker, Lyn R.
Stimulated by practical concerns in the use of order restricted estimators, we study some bias issues of isotonic estimators of ordered parameters. We obtain explicit expressions for biases of order...
Preservation of some partial orderings under the formation of coherent systems
Nanda, Asok K., Jain, Kanchan, Singh, Harshinder
The reversed (backward) hazard rate ordering is an ordering for random variables which compares lifetimes with respect to their reversed hazard rate functions. In this paper, we have given some...
Estimation of the entropy of a multivariate normal distribution
Misra, Neeraj, Singh, Harshinder, Demchuk, Eugene
Motivated by problems in molecular biosciences wherein the evaluation of entropy of a molecular system is important for understanding its thermodynamic properties, we consider the efficient...
Testing for Second-Order Stochastic Dominance of Two Distributions
Kaur, Amarjot, Singh, Harshinder
A distribution function F is said to stochastically dominate another distribution function G in the second-order sense if , for all x. Second-order stochastic dominance plays an important role in...
