| Abstract: | The hypothesis testing method is used to test if there are systematic residuals in the model of the measurement adjustment,and semi-parameter model is used to separate the systematic residuals for the mathematic models with systematic residuals.The cubic spline function is used to fit systematic residuals and parameterize systematic residuals and refine the model of the error compensation.The conclusion shows that the semi-parameter model can effectively correct the systematic residuals in the positive para... |
