Abstract

This corrigendum focuses on the correction of numerical results derived from Poisson-Lomax Distribution (PLD) originally proposed by Al-Zahrani & Sagor (2014). Though the mathematical properties and derivations by Al-Zahrani & Sagor (2014) were immaculate but during the execution of the R codes using Monte Carlo simulation some anomalies occurred in the calculation of the mean values. The same anomalies are addressed in the present corrigendum. The outcome of the corrigendum will provide basic guidelines for the academia and reviewers of various journals to match the numerical results with the shape of the probability distribution under study. The results will also emphasize the fact that code writing is a cumbersome process and due diligence be exercised in executing the codes using any programming language. Relevant R codes are appended in Appendix 'A'.

Key words: Monte Carlo method; Poisson-Lomax distribution; probability distribution

Resumen

Esta corrección se centra en la corrección de los resultados numéricos derivados de la Distribución Poisson-Lomax (PLD) propuesta originalmente por Al-Zahrani & Sagor (2014). Aunque las propiedades matemáticas y las derivaciones de Al-Zahrani & Sagor (2014) son correctas, durante la ejecución de los códigos R utilizando la simulación de Montecarlo se produjeron algunas anomalías en el cálculo de los valores medios. La corrección proporciona directrices para que académicos y revisores hagan coincidir los resultados numéricos con la forma de la distribución de probabilidad objeto de estudio. Los resultados también ponen de relieve el hecho de que la escritura y ejecución de los códigos, en cualquier lenguaje de programación, es un proceso engorroso que requiere precaución. Los códigos R relevantes se adjuntan en el Apéndice 'A'.

Palabras clave: Distribución Poisson-Lomax; distribución de probabilidad; método de Montecarlo
