Abstract
A non-proportional hazards regression model is considered in which the structural parameter is the vector of regression coefficients and the nuisance parameter is a vector of arbitrarily high dimension, The asy mptotic distribution as well as the efficiency and consistency of join tly (implicitly) defined estimators of the structural and nuisance par ameters of the model are established.
