General frameworks and specific examples such as the Cox regression model will be considered. I will explore a model where the hazard rates of the treatment and control groups start out equal at the time the treatment is introduced and then diverges continuously as time increases. A semiparametric model with bounded random variables is also  considered and it is shown that in this model empirical maximum likelihood estimates converge at a rate of n rather than usual rate root(n).\n\u003C\/p\u003E\n\u003Cp\u003EVarious likelihoods in use for semiparametric models will be discussed and compared.
