Abstract: This study introduces the Log-Dagum Singh Maddala (4P) distribution, a significant contribution to the field of continuous distributions. We investigate its statistical properties including probability density, hazard rate, survival functions, quantiles, and order statistics. The distribution is thoroughly characterized using multiple approaches and maximum likelihood estimation is used to determine the parameters. The model's effectiveness is evaluated using three real-world datasets and a comparative analysis with established distributions highlights its advantages. The results confirm the excellence of the proposed model demonstrating its practical significance in real data analysis.
