摘要
给出半参数非线性回归模型的t-型估计及其EM算法,同时获得估计的相合性及渐近正态性.并基于EM算法中的Q函数,研究了半参数非线性回归模型的统计诊断方法.最后,用一个模拟例子和一个实际例子验证了本文提出的t-型估计和诊断方法的有效性.
t-type regression estimators for the semiparametric nonlinear models were defined,and the EM algorithm for the t-type estimators were given.Moreover,the consistency of t-type regression estimators was obtained.And on the basis of the Q-function in the EM algorithm,statistical diagnostics methods were investigated.Finally,the proposed algorithm was tested by simulation analysis and by a real data sample.
