smartpls 3 的PLS功能里直接由 特定的间接效应、直接效应。直接显示T值和P值，包括bootstrap的95%置信区间，然后直接可以判断。
间接效应显著，看直接效应。直接效应也显著则部分中介，直接效应不显著则为完全中介。
原话：
In SmartPLS, the results of the PLS-SEM algorithm and the bootstrap procedure include the direct, the total indirect effect, the specific indirect effects, and the total effect. These outcomes, which are available in the SmartPLS results reports, permit conducting a mediator analysis (e.g., as suggested by Hair et al. 2017). Note that the SmartPLS results allow analyzing both single and multiple mediation models (i.e., parallel and serial mediation).
