摘 要: 在约束条件下利用拟似然估计方法对AR(2)模型的参数进行统计推断,研究了拟似然估计α^和约束拟似然估计α^*的相合性及渐近正态性,并给出了AR(2)模型参数序关系的假设检验方法及模拟结果. We studied the parameter estimation for AR(2) model under simple order restriction via quasi-likelihood method.The strong consistency and asymptotic property of quasi-likelihood estimator and the restriction quasi-likelihood estimator * were discussed.Furthermore,we considered the problem of testing homogeneity of parameters against the simple order restriction,and also gave a simulation.
