WebThis function is called the mean residual life function (MRL function for short). Definition 2.2 Let F be a distribution function on R. Consider the measure vp on (the Borel a - field of) R such that for every Borel set B. This measure is called the hazard measure related to F. WebThe term reliability function is common in engineering while the term survival function is used in a broader range of applications, including human mortality. The survival function is the complementary cumulative distribution function of the lifetime.

WebAbstract: We propose here a smooth estimator of the mean residual life function based on randomly censored data. This is derived by smoothing the product-limit estimator using the Chaubey-Sen technique (Chaubey and Sen (1998)). The resulting estimator does not suﬀer from boundary bias as is the case with standard kernel smoothing.
