Burr III Scaled Inverse Odds Ratio-Rayleigh Distribution for Modeling Asymmetric Engineering, Disease Surveillance and Epidemiological Data

Modeling real-world dataâĂŤparticularly in fields like reliability engineering, survival analysis, and epidemiologyâĂŤoften requires distributions with the flexibility to accommodate heavy tails, skewness, and a range of hazard rate behaviors. Classical models such as the Rayleigh distribution, while analytically tract...

Mixed-Record Stress-Strength Reliability for the Poisson-Exponential Distribution

This study develops classical and Bayesian inference for the stress–strength reliability parameter R=P(X>Y) under an asymmetric mixed-record sampling scheme for the Poisson-exponential distribution. The strength variable is observed through upper record values, whereas the stress variable is represented by lower record...
