Abstract
The permutation algorithm allows to test if predefined data groups have statistically significant differences in their groupspecific parameter estimates (e.g., outer weights, outer loadings and path coefficients). It also supports the MICOM procedure for analyzing measurement invariance.
Description
The purpose of using the permutation routine in SmartPLS is twofold:
(1) It allows conducting a PLSSEM 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 groupspecific PLSSEM results have statistically significant differences.
(2) It allows conducting the PLSSEM measurement invariance assessment as suggested by Henseler, Ringle, and Sarstedt's (2015) MICOM routine. Thereby, you can substantiate that significant differences in the groupspecific PLSSEM results do not stem from differences in the constructs (e.g., customer loyalty) across groups.
The results report of the permutation routine in SmartPLS includes the outcomes of the PLS multigroup analysis (using the permutation test) and the MICOM results for assessing measurement invariance.
Permutation Settings in SmartPLS
Select Groups
The selected groups will be assessed for significant differences in the parameter estimates (e.g., outer weights, outer loadings and path coefficients) and measurement invariance (MICOM).
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 PLSSEM multigroup analysis.
Permutations
Permutations are created with observations randomly drawn from the original set of data (without replacement). More precisely, n observations are drawn without replacement and assigned to Group A; all remaining observations are assigned to Group B. It is important to note that n equals the number of observations of Group A in the original dataset. The remaining data that are assigned to Group B also have the same number of observations that Group B has in the original dataset. Consequently, in each permutation run, the groupspecific sample sizes remain constant and equal the size of each group in the original dataset.
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.
Test Type
When using the permutation procedure's results to create confidence intervals, it is important to determine, if you wish conducting a onetailed or twotailed (or onesided or twosided) significance test. This selection also affects p value computation.
The default value is two tailed.
Significance Level
This option allows you to specify the significance level that is used for the confidence interval computations.
The default values is 0.05.
Do Parallel Processing
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.
