The purpose of using the permutation routine in SmartPLS 3 (Ringle, Wende, and Becker, 2015) is twofold:
(1) It allows conducting a PLS-SEM multigroup analysis (Hair et al., 2018; Sarstedt, Henseler, and Ringle, 2011) as suggested by Dibbern and Chin (2005) and Chin and Dibbern (2010). Thereby, you can decide if group-specific PLS-SEM results have statistically significant differences.
(2) It allows conducting the PLS-SEM measurement invariance assessment as suggested by Henseler, Ringle, and Sarstedt’s (2016) MICOM routine. Thereby, you can substantiate that significant differences in the group-specific PLS-SEM results do not stem from differences in the constructs (e.g., customer loyalty) across groups.
The results report of the permutation routine in SmartPLS 3 includes the outcomes of the PLS multigroup analysis (using the permutation test) and the MICOM results for assessing measurement invariance.
The data group selected under Group A will be compared against the data group selected under Group B.Note: If the combo box for group selection is empty, you need to double click on the dataset (see SmartPLS project window). Then, use the available options to generate groups of data for the PLS-SEM multi-group analysis.
To ensure stability of the results, the number of permutations should be large. For a quick initial assessment, one may choose a smaller number of permutation subsamples (e.g., 500 or 1,000). For the final results preparation, however, one should use a large number of permutations (e.g., 5,000).
Note: Larger numbers of permutations increase the computation time.
The default value is 1,000.
When using the permutation procedure's results to create confidence intervals, it is important to determine, if you wish conducting a one-tailed or two-tailed (or one-sided or two-sided) significance test. This selection also affects p value computation.
The default value is two tailed.
This option allows you to specify the significance level that is used for the confidence interval computations.
The default values is 0.05.
Permutation will be performed on multiple processors (if your computer offers more than one core). Using parallel computing considerably reduces computation time.
The default setting uses parallel processing.
