1 a 24 On the Performance Evaluation of Different Measures of Association Evaluación de diferentes medidas de asociación Muhammad Riaz1,a , Shahzad Munir2,b , Zahid Asghar2,c 1 Department of Mathematics and Statistics, King Fahad University of Petroleum and Minerals, Dhahran, Saudi Arabia 2 Department of Statistics, Quaid-i-Azam University, Islamabad, Pakistan Abstract In this article our objective is to evaluate the performance of different measures of associations for hypothesis testing purposes.
We have considered different measures of association (including some commonly used) in this study, one of which is parametric and others are non-parametric including three proposed modifications.
Performance of these tests are compared under different symmetric, skewed and contaminated probability distributions that include Normal, Cauchy, Uniform, Laplace, Lognormal, Exponential, Weibull, Gamma, t, Chi-square, Half Normal, Mixed Weibull and Mixed Normal.
Performances of these tests are measured in terms of power.
We have suggested appropriate tests which may perform better under different situations based on their efficiency grading(s).
It is expected that researchers will find these results use...
