The paper introduces a new distribution called the Lomax-Weibull distribution using the competing risk approach of constructing lifetime distributions. Some structural and mathematical properties of the proposed lifetime distribution are considered. Parameter estimation of the Lomax Weibull distribution is obtained using maximum likelihood estimation. The applicability and flexibility of the new distribution in lifetime analysis is illustrated with the aid of two real life examples.
