Abstract:

We consider the parametric estimation with right-censored competing risks data and with masked failure cause. We propose a new model, called the random partition masking model. We propose a wide class of parametric distribution families of the failure time and cause. A feasible algorithm for the MLE is proposed for some special cases. We also study the asymptotic properties of the MLE under the new model.
