RIAZ, MUHAMMAD; MUNIR, SHAHZAD  y  ASGHAR, ZAHID. On the Performance Evaluation of Different Measures of Association. Rev.Colomb.Estad. [online]. 2014, vol.37, n.1, pp.1-24. ISSN 0120-1751.  https://doi.org/10.15446/rce.v37n1.44353.

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 useful in decision making.

Palabras clave : Measures of association; Non-Normality; Non-Parametric methods; Normality; Parametric methods; Power.
