A bathtub equation can be used to model data that exhibits infant mortality, chance failures, and wear out. This technique allows for the simultaneous solution of equation parameters affecting the product’s life. The bathtub equation treats a portion of the population as a competing risk mixture. This allows total failure of the infant mortality population without causing complete failure of the entire population. Chance and wear out failures are included by using a compound competing risk mixture.
