Abstract

Background of the Study: Quest to extend existing probability distributions to allow for more flexibility in data modelling is never ending.
 Aims: This study extends the Ailamujia distribution using quadratic transmutation map to propose a new 2-paramter lifetime distribution.
 Methodology: Shapes of the density function and the hazard rate function of the new propositions are obtained. Some mathematical properties of the new distribution are also obtained.
 Results: Application of the distribution to four lifetime datasets reveals that the distribution competes favourably with other related distributions.
 Conclusion: The new distribution competes favourably with the existing distributions in data modelling.
