对pls 结构方程不太熟悉，求助大神！！！先行谢过！！！
二阶潜变量（一阶反映二阶构成）如何应用smart pls 分析测量模型？有文献如下说：As latent variable scores are determinate in PLS path analysis, latent variables scores for lower-order latent variables can be obtained (Chin 1998; Tenenhaus et al. 2005), which can subsequently be used as manifest variables for the higher-order latent variables.

PLS pathanalysis 怎样获得低阶潜变量得分？高阶潜变量又没有直接测量指标？是不是要用到重复指标法或者两阶段法？求知道的大神给些指导！！！
