摘要
考虑一列非线性回归模型，对非线性项使用了一阶近似进而使模型转化为线性模型，得到了模型ＬＳ估计的迭代解，考察了解的渐近性质，证明了过程的可行性，最后对非线性项的特殊情形作了描述，其中１种情形可得到ＬＳ估计的精确解。
For partially nolinear models,the mode was m odified by transforming nonlinear function in model funtion into linear function ,and L.S estimator was obtained.The iteration procedure for estinating the param ters was indicated by considering the propertied of estimator.A special class of nonlinear models was considered at last.
