【Abstract】 On the basis Of analyzing the three simple measurement methods and geometric characters of the model nonlinearity , the paper firstly gives the two nonlinearities of the model - inherent model nodriearity and the parameter effect nonlinearity with its measurement method . Thence, it discusses the nonlinearity of the parameter vectors and the residual error vectors. Finally a method of diagnosing the model noulinearity is proposed .更多还原
