The Shapes of a Probability Density Function and Its Hazard Function

Abstract

The shape of a probability density function restricts that of its hazard function, and vice versa. We are concerned with the six specific ‘shapes’: increasing, decreasing, unimodal, anti-unimodal, increasing-decreasing-increasing, and decreasing-increasing-decreasing.
