【 摘 要 】

Motivated by regression analysis of censored survival data, we develop herein a general asymptotic distribution theory for estimators defined by estimating equations of the form Sigma(i=1)(n) xi(w(i), theta, G(n);) = 0, in which w(i) represents observed data, theta is an unknown parameter to be estimated, and G(n) represents an estimate of some unknown underlying distribution. This general theory is used to establish asymptotic normality of synthetic least squares estimates in censored regression models and to evaluate the covariance matrices of the limiting normal distributions.
