摘要
本文指出现有模型拟合方法对结果误差估算的不足之处,就CaltechVLBI软件包中的MOD-ELFIT程序,对模型拟合算法做了简要分析,并引入蒙特卡罗(MonteCarlo)方法对模型拟合参数的置信度作了检验。
The inadequacy in uncertainty estimation of parameters from the model fittingtechnique is addressed. Model fitting algorithm is analyzed with emphasis on MODELFIT program in the Caltech VLBI package. A Monte Carlo method is introduced to test the robustness of model parameters.
