Additive negative Perks–Lindley distribution with increasing, decreasing and bathtub-shaped hazard rate function

Key Points

• The study introduces a novel additive model in survival analysis, showing diverse hazard rate functions including increasing and decreasing patterns.
• Critical metrics highlight the diverse applications of the Perks–Lindley distribution in modeling survival data effectively, particularly the bathtub-shaped hazard rate.
• Observational analysis explores the implications of varying hazard rates within the framework of survival analysis, enhancing understanding of data behavior.
• These findings suggest further exploration of the additive models to refine statistical modeling and improve accuracy in practical applications.
