【摘要】：双因子模型和高阶因子模型,作为既有全局因子又有局部因子的两个竞争模型,在研究中得到了广泛应用。本文采用Monte Carlo模拟方法,在模型拟合比较的基础上,比较了效标分别为外显变量和内潜变量时,两个模型在各种负荷水平下预测准确度的差异。结果发现,两种模型在拟合效果方面无显著差异;但在预测效度方面,当效标为显变量时,两个模型的结构系数估计值皆为无偏估计;而效标为潜变量时,高阶因子模型表现优于双因子模型:高阶因子模型的结构系数为无偏估计,双因子模型的结构系数估计值则在50%左右的情况下存在偏差。
[Abstract]:Two-factor model and high-order factor model, as two competitive models with both global and local factors, have been widely used in the research. In this paper, Monte Carlo simulation method is adopted. On the basis of model fitting and comparison, the difference of prediction accuracy between the two models under various load levels is compared when the effect criteria are explicit variables and latent variables respectively. There was no significant difference in fitting effect between the two models. However, in the aspect of prediction validity, when the criterion is explicit, the estimation of the structural coefficients of the two models is unbiased. The higher order factor model is better than the double factor model when the effect scale is latent variable. The structure coefficient of the higher order factor model is unbiased estimate. On the other hand, there is a deviation in the estimation of the structure coefficient of the two-factor model in the case of about 50%.
