Mediation Tests

After fitting a model with at least one mediator variable, the question arises whether the mediator variable's role is significant?
To answer this question, you need to do mediation tests. SEM-PLS software performs mediation tests for you.

For example, you are researching the GDP index. GDP latent variable is made from three measurement variables "GDP Nominal," "GDP Real," and "GDP per capita." In this regard, GDP_1 and GDP_2 will be the latent variable of GDP with a lag of one year and two years, respectively. A model with the mediating role of GDP_1 can be considered. If the P-value of the test is less than 0.05, the mediating role of GDP_1 variable is accepted with a confidence level of 95%.
