Bathtub concept in health sciences: A comment

Abstract

Bathtub shape has important connotations in public health and the concept could be reflected in two novel ways: (1) engineering (2) epidemiological model. Typical bath-tub curve is a combination of three failure rates, that is, decreasing, constant, and increasing failure rate, and different techniques are utilized to reduce these failures. This brief study highlights the concept of bath-tub, related theory, application, and how data modeling could be undertaken considering bath-tub failure rate.
