Using WarpPLS in E-Collaboration Studies: Descriptive Statistics, Settings, and Key Analysis Results

A new article discussing WarpPLS is available. The article is titled “Using WarpPLS in E-Collaboration Studies: Descriptive Statistics, Settings, and Key Analysis Results”. It has been recently published in the International Journal of e-Collaboration. A full text version of the article is available here as a PDF file. Below is the abstract of the article.

This is a follow-up on a previous article (Kock, 2010b) discussing the five main steps through which a nonlinear structural equation modeling analysis could be conducted with the software WarpPLS ( Both this and the previous article use data from the same e-collaboration study as a basis for the discussion of important WarpPLS features. Unlike in the previous article, the focus here is on specific features related to saving and analyzing grouped descriptive statistics, viewing and changing analysis algorithm and resampling settings, and viewing and saving the various minor and major results of the analysis. Even though its focus is on an e-collaboration study this article contributes to the broad literature on multivariate analysis methods, in addition to the more specific research literature on e-collaboration. The reason for this is that the vast majority of relationships between variables, in investigations of both natural and behavioral phenomena, are nonlinear; usually taking the form of U and S curves. Structural equation modeling software tools, whether variance- or covariance-based, typically do not estimate coefficients of association based on nonlinear analysis algorithms. WarpPLS is an exception in this respect. Without taking nonlinearity into consideration, the results can be misleading; especially in complex and multi-factorial situations such as those stemming from e-collaboration in virtual teams.

Transitioning from WarpPLS 1.0 to 2.0

Transitioning from version 1.0 to 2.0 of WarpPLS is very easy. Even though both can be installed and ran on the same computer, and should not interfere with each other, I recommend using only the latest version.

There is no need to uninstall version 1.0, but if you want to do so you can follow the instructions at the beginning of the User Manual for version 1.0.

Version 1.0 users can enter the same license information as for version 1.0; it will work for version 2.0 for the remainder of their license periods.

Project files generated with version 1.0 can be used with version 2.0, but only after running Step 5 again. This is needed because version 2.0 generates additional estimates.
