A New Estimation Algorithm for Box-Cox Transformation Cure Rate Model and Comparison With EM Algorithm
Suvra Pal, Souvik Roy
In this paper, we develop a new estimation procedure based on the non-linear conjugate gradient (NCG) algorithm for the Box-Cox transformation cure rate model. We compare the perfo…
