摘要
Abstract
In this paper,the asymptotic relative efficiency of regression coefficient estimation was studied for the composite quantile regression model of individual fixed effect in panel data.The ratio of trace of covariance matrix of composite quantile regression estimation and least squares estimation was calculated. The results showed that the asymptotic phase of composite quantile regression was relative to that of least squares method. The ratio of efficiency to efficiency was more than 70%. This paper also applied Zous idea of adaptive lasso proposed in 2008 to the composite quantile regression model of individual fixed effect in panel data,constructed the adaptive lasso penalty composite quantile regression estimation,and proved the asymptotic nature of the estimation under appropriate conditions.关键词
