| چکیده | ||
| This paper introduces a two-parameter generalization of the sine-modified Lindley distribution by incorporating a shape parameter α. This extended model retains the flexibility of the sine-modified Lindley distribution while enhancing its ability to model a wider range of lifetime and reliability data. The distribution’s properties, including probability density function, cumulative distribution function, survival function, moments, and hazard rate function, are derived. Maximum likelihood estimation is used for parameter estimation, and its performance is evaluated through simulations. The model is applied to real-world datasets and compared with existing lifetime distributions using goodness-of-fit criteria. Results demonstrate its superiority in modeling skewed and heavy-tailed data. | ||
