Study on Model Error of Adjustment System and Its Identified Method

The estimated value of parameters' is optimized and unbias only if the error of ad-justment model is not outstanding. Some theory problems affecting parameters estimation are discussed in this paper. Influence and transformation between errors of stochastic and functional models is pointed out as well. For choosing the best adjustment model, a theory formula, which is different from the methods in existing literatures, used to estimate and identify model error is proposed by the author. Based on that theory formula, an applied one and a method of selecting the best model of adjustment system are given.
