According to the characteristics of data collection, generalizedleastsquares method was used to calibrate model.
根据采集数据的特点，采用广义最小二乘法标定模型。
2
Direct parameters were attained from the measurement data, and hidden parameters of the model were calibrated using the generalizedleastsquares method.
模型的直接参数通过实测数据获得， 隐含参数利用非线性最小二乘法拟合反求获得。
3
By employing the concept of statistical curvatures, the information loss of the maximum likelihood estimator and the generalizedleastsquares estimator is investigated.
