摘要:
SummaryMethods of detecting influential observations for the normal model for censored data are proposed. These methods include one‐step deletion methods, deletion of observations and the empirical influence function. Emphasis is placed on assessing the impact that a single observation has on the estimation of coefficients of the model. Functions of the coefficients such as the median lifetime are also considered. Results are compared when applied to two sets of dat
