摘要: 对半参数线性模型Y=θ+g(T)+ε根据PMLE作者构造了θ1的二阶渐近有效估计,这里T和ε独立,g(·)和θ1未知,ε的分布密度已知且均值为0方差是σ2。Abstract: In this paper, the authors oonstruot seoond order asymptotically effluent estimator of θ1 baaed on PMLB for the semiparametric regression model Y=θ+g(T)+ε, where T and ε are independent, g is unknown, the density function g(·) of ε is known with mean 0 and variance σ2
