摘要:
Methods are proposed for deriving unbiased estimating equations for the parameters of interest in a statistical model which includes further incidental or nuisance parameters. Pivot-like quantities eliminate the dependence on the incidental parameters and functions are derived which give estimating equations which are most efficient in a certain sense. These equations involve the incidental parameters, which are then replaced by estimators. The methods overcome some of the difficulties encountered in likelihood and least squares estimation when there are many incidental parameters, and the theory reduces the likelihood and least squares estimation when there are none. The optimality results apply to these methods too. Examples are discussed.
