Abstract：Through the variable substitution, linear regression models with two parameters are given in space of nonlinear functions. Based on the model establishment and significance test for simple linear regression, the comprehensive evaluation index is put forward for regression effect with different sample data. With measured data and Matlab program, the relation between cumulative deformation and monitoring date at each stage is analyzed. Then, the linear regression method is verified feasible for monitoring data analysis and realtime prediction.
