【摘要】 从解决大学生网络成瘾和抑郁相互影响关系的研究出发,构建了有调节的中介潜变量的循环效应模型.为对模型变量进行效应大小的分析和比较,推导出模型参数的标准化估计.运用我们提出的基于配方约束的潜变量回归的确定性线性算法来计算潜变量的值,避免了交互潜变量计算时观测变量的配对问题.对模型参数的OLS估计可能不具有一致性和无偏性进行了证明,并给出了解决问题的相应算法.总结出模型的算法步骤和变量的效应检验步骤.最后进行了数值模拟,验证了模型的合理性.更多还原

【Abstract】 The potential variable’s circular effect model with moderated mediator is built to study the interactional correlation between college students’ depression and internet addiction.In order to analyse and compare the effect size of the variables in model,the standardized estimation of parameters is deduced.The potential variables are calculated by using the definite linear algorithm for potential regression based on prescription condition that we propose.It avoids partnerring the observation variables to calculate the interactive potential variables.That the ordinary least squares estimation of the parameters in the model are unbiasedness and uniformity are proved,and the relevant algorithm is gived to solve this problems.The algorithmic steps of the model and the test procedure of the effect of variables are summarized.Finally,the numerical simulation is carried out to verify the rationality of the model.更多还原
