PLS Applications Symposium; 11 - 13 April 2018; Laredo, Texas


PLS Applications Symposium; 11 - 13 April 2018; Laredo, Texas
(Abstract submissions accepted until 15 February 2018)

*** Only abstracts are needed for the submissions ***

The partial least squares (PLS) method has increasingly been used in a variety of fields of research and practice, particularly in the context of PLS-based structural equation modeling (SEM). The focus of this Symposium is on the application of PLS-based methods, from a multidisciplinary perspective. For types of submissions, deadlines, and other details, please visit the Symposium’s web site:

*** Workshop on PLS-SEM ***

On 11 April 2018 a full-day workshop on PLS-SEM will be conducted by Dr. Ned Kock and Dr. Geoffrey Hubona, using the software WarpPLS. Dr. Kock is the original developer of this software, which is one of the leading PLS-SEM tools today; used by thousands of researchers from a wide variety of disciplines, and from many different countries. Dr. Hubona has extensive experience conducting research and teaching topics related to PLS-SEM, using WarpPLS and a variety of other tools. This workshop will be hands-on and interactive, and will have two parts: (a) basic PLS-SEM issues, conducted in the morning (9 am - 12 noon) by Dr. Hubona; and (b) intermediate and advanced PLS-SEM issues, conducted in the afternoon (2 pm - 5 pm) by Dr. Kock. Participants may attend either one, or both of the two parts.

The following topics, among others, will be covered - Running a Full PLS-SEM Analysis - Conducting a Moderating Effects Analysis - Viewing Moderating Effects via 3D and 2D Graphs - Creating and Using Second Order Latent Variables - Viewing Indirect and Total Effects - Viewing Skewness and Kurtosis of Manifest and Latent Variables - Viewing Nonlinear Relationships - Solving Collinearity Problems - Conducting a Factor-Based PLS-SEM Analysis - Using Consistent PLS Factor-Based Algorithms - Exploring Statistical Power and Minimum Sample Sizes - Exploring Conditional Probabilistic Queries - Exploring Full Latent Growth - Conducting Multi-Group Analyses - Assessing Measurement Invariance - Creating Analytic Composites.

Hello Ned,
I am a Ph.D. Student from India and is currently learning WarpPLS for my analyses. Getting results with CBSEM was very difficult because of the large number of variables I have as DV, IV, and mediators. WarpPLS seems to be a simple yet comprehensive analytic tool and thank you for it. I have multiple dependent variables and two mediators in my model.Is it right if I carry out multiple mediation for each of my dependent variables individually rather than analyzing everything at one go? As far as R-Squared is concerned, do I have to report it for the direct as well as the mediated model for each dependent variable? I am sorry if my questions are silly, but I hope you will spend a minute or two to answer this. Also, if there is only one IV in the model,how is effect size calculated?

Hi Anon.

I am not sure if I understand your question. The video below may be relevant for you. It is one of the many resources available from warppls.com.

It is also a good idea to take a look at the article below, available as a PDF file from warppls.com.

Kock, N. (2014). Advanced mediating effects tests, multi-group analyses, and measurement model assessments in PLS-based SEM. International Journal of e-Collaboration, 10(3), 1-13.

You can also conduct a more sophisticated analysis that includes related mediation and moderation tests by employing the “indirect and total effects” and “full latent growth” features of WarpPLS. I hope that the short videos linked below can be of use in connection with this.

Explore Full Latent Growth in WarpPLS

Let us say you have a model with the direct links A > B and B > C, and you want to test the mediation effect A > B > C and the moderation effect M > (A > B > C).

With the “indirect and total effects” and “full latent growth” features of WarpPLS, you would do the following:

1. Test the significance of the mediating effect A > B > C; using the “indirect and total effects” feature.

2. Test the significance of the moderating link M > (A > B); using the “full latent growth” feature.

3. Test the significance of the moderating link M > (B > C); using the “full latent growth” feature.

If test 1 suggests significant mediation, then tests 2 and 3 become more telling. In that case, if either test 2 or 3 suggests significant moderation (or growth), then you have significant moderated mediation. Moreover, by employing this analysis approach you can tell whether the moderation is significant with respect to the link A > B, the link B > C, or both.

This provides more detailed results than a single test of moderated mediation test of: M > (A > B > C). In this latter type of test, which seems to have been promoted a lot lately, you cannot tell which of the segments of an indirect relationship path are being moderated.

I hope this helps.

Thank You, Ned for your answer. In my model, there is one IV which is a second-order construct with four first-order factors. I am using the scores of this second order construct for further analysis. Additionally, there are two mediators, M1 and M2 and four DVs. I was asking whether it is right to carry out the test for mediation for each DV separately. For example, mediation with IV, M1 and M2 and DV1. Similarly for all other DVs. I understand multiple mediation but I am not sure when we have multiple DVs. When we report our findings, is it appropriate to report separately the findings for each DV? So, in short, how do we do this when we have multiple mediation and multiple DVs?

Thank you in advance.

This seems to be related to the issue of isolating mediating effects, covered in the video below, correct?

As for reporting the findings, I don't see a problem with using one approach or the other. The more straightforward the presentation, the better, as long as no important details are missing.

Hi Ned,
If I want to just attend the PLS workshop on the 11th, do I need to register through the Western Hemisphere conference? Are there still seats left?
Thanks!
James Gaskin

Hi James. Yes, you register to the PLS workshop through the WHT Conference. If you have any problems, please contact them directly by email or phone (see below). Amy Palacios is the main person behind the organization.
