方法采用因子分析和线性结构方程模型分析肾结石发病的危险因素,并进行模型拟合与评估。
Methods Risk factors of renal calculi were analyzed by factor analysis and linear structural relation model, followed by fitting and evaluating the model.
By using this technique, the dynamic uncertainty contribution of an analytical measurement system comprises of uncertainties of quality control (QC) sample measurements and linear fitting.
