Censorship in the random censorship model is described by a pro-portionality function (t), where (t) is a function of the survival function S T of the lifetimes, and the survival function S C of the censoring times. An estimator of (t) is proposed and asymptotic properties of the estimator are ascertained. A conndence band for (t) using the bootstrap is derived. We also develop a bootstrap test of H 0 :(t)=, where the constant value of is unspeciied. The results are applied to an actual dataset.
