The Poly-Weibull distribution is a probability distribution that generalizes the Weibull distribution. It is defined as a mixture or a combination of multiple Weibull distributions, allowing it to capture a wider variety of behaviors in data, especially when the hazard function or failure rates vary significantly across different scenarios. ### Key Characteristics: 1. **Flexible Shape**: The Poly-Weibull distribution can model data showing increasing, decreasing, or constant failure rates, which makes it useful in reliability analysis and survival studies.
