Abstract
The problem of trend change in the failure rate is great interest in the reliability and survival analysis. In this paper we develop a test statistic for testing whether or not the failure rate changes its trend using random censored date. The sasymptotic normality of the test statistic is established. The efficiency values of loss due to censoring are discussed.
