Heart pacemaker wear life model based on frequent properties and life distribution
Qiao-Ling Tong, Xue-Cheng Zou, Jin Tang, Heng-Qing Tong
Abstract: The lifetime of heart pacemaker is important for patient and researcher. To forecast the lifetime of heart pacemakers we must determine its distribution regularity. In this paper, a heart pacemaker wear life model is introduced by using frequency property, and a life distribution is presented. The parametric properties of the density are studied. The moment estimator with negative order is used, which is just the maximum likelihood estimator. A new method of parameter estimate, F estimate of parameter, is proposed. This method is suitable to both truncated samples and complete samples, whether or not the distribution can be transformed into a standard distribution without any parameters.
