| Abstract: | The results of adjustment and their statistical features will be influenced by incorrect stochastic model. Supposed the functional model is correct, the influence on the statistic of test for uniform variance with incorrect stochastic model is analyzed in detail and its formula is derived. The conclusion given in this paper will help to implement the teaching contents of adjustment and test the correction of adjustment model in practice. |
