A Note on the Proof by H. E. Daniels of the Asymptotic Efficiency of a Maximum Likelihood Estimator
关于 Daniels 最大似然估计渐近有效性证明的注记
A corrected proof of an important preliminary result of Daniels (1961) is presented. Daniels's work, showing that a well-behaved second dericative of the expected log likelihood function, rather than of the log likelihood function, is the key to asymptotic efficiency, is thus complete.
