Abstract

In this paper the exponential life time model is used as a competing risk model. The causes of failures are assumed independent. For analysis of the data Type-I progressive interval censoring is used. Point estimation and interval estimation of the parameters and survival function are made using maximum likelihood and bootstrap methods. Non-parametric estimation is also considered. A real life example is provided to illustrate the results obtained in the paper.

Keywords

Progressive Type-I, interval censoring, maximum likelihood, bootstrap, survival function, nonparametric.
