Identifiability in masking models for competing risks data.
Abstract
We consider the estimation problem
with competing risks data and masked failure cause. We investigate the
identifiability issue for two popular models in the literature on
the MCR data. A finding of the paper is that the parameters in the
model proposed by Flehinger et al. (2001) is not identifiable
unless additional constraints such as the stage-2 model are imposed on the
parameters.
