Abstract | ||
Abstract Recent research has increasingly concentrated on the transformation of lifetime distributions employing the Dinesh–Umesh–Sanjay (DUS) technique. This study presents an innovative model that is based on the exponentiation of the DUS transformation, resulting in a distribution derived from the exponentiated gamma (EG) distribution. We conducted a rigorous examination of the statistical properties of the DUS-EG distribution. Utilizing the maximum likelihood estimation approach, we estimated the model parameters and performed a simulation study to evaluate the efficacy of the estimators. The proposed model was validated through a comprehensive analysis of empirical data. | ||
