AbstractSeveral statistical models have been proposed to study effects of different covariates in the failure of water pipes. In this paper, three statistical models, the Weibull proportional hazard model (WPHM), the Cox proportional hazard model (Cox-PHM), and the Poisson model (PM), were considered. Curve fitting techniques were proposed for estimation of a baseline hazard function equation for the Cox-PHM to allow for its application in break prediction. The water main failure in the City of… CONTINUE READING
