考虑了变系数单指标模型,它是部分线性单指标模型的推广.本文提出了未知参数的对数似然比统计量,在适当的条件下,证明了该统计量依分布收敛到X^2分布,根据该结果,可以构造未知参数的置信域.
Empirical-likelihood-based inference for the parameters in varying-coefficient single-index model is investigated. The model can be seen as a generalization of the partially linear single-index model. In this paper, we propose the empirical likelihood ratio statistics,it is shown that the statistics follow asymptotically X^2 -distribution and the confidence regions are constructed.
