基于经验似然的方法构造了检验统计量,对非参数回归模型中的误差进行了相关性假设检验,获得了零假设下检验统计量的渐近分布为χ^2分布.模拟计算表明相关性假设检验的经验似然方法具有较好的功效.
Based on the empirical likelihood ratio test is proposed to test the autocorrelation of the random errors in nonparametric regression model. The test statistic has an asymptotically chi-square distribution. A simulation computation is carried out to illustrate the performance of the new test.
