title: Application of a stochastic model to ascertain the truncation bias and systematic component of variation in closed birth interval.
abstract: "In this paper an attempt is made to estimate the truncation bias in the mean length of closed birth interval caused by the termination of observations after [a] certain time, through the application of a stochastic model based on certain simplified assumptions.  The approach is further evolved to determine the relative contributions of...chance and systematic components to the variance of closed birth interval when the fecundability parameter follows a priori distribution.  Some numerical results have also been presented for the purpose of illustration."
