New R-Package SEMinR: A Substitute to AMOS and SmartPLS

[Neeraj Kaushik]

Dear Friends

SEM has become the norm of the day and we have 3 proprietary software: IBM-AMOS, SmartPLS and Adanco

We've some R-packages which provides almost the same/similar results to the 3 proprietary software:

• lavaan (LAtent VAriable ANalysis) as an substitute to IBM-AMOS [Explained on https://www.youtube.com/watch?v=kf0yOJr3wtk&list=PLzUJUtTJcj8S0hg4Nz-OxQAME3QEg-nFt&index=53]
• plspm (Partial Least Square Path Modelling)  as an substitute to SmartPLS (Explained on https://www.youtube.com/playlist?list=PLzUJUtTJcj8SbPC27q9DlVe0lS7OlSYV0]
• cca (Confirmatory Composite Analysis)  as an substitute to Adanco [Explained on https://www.youtube.com/playlist?list=PLzUJUtTJcj8RRheMKJ873DxdRURmVdi0S]

But now we have one new R-package SEMinR which single handedly provides the same results that of 

• CFA (IBM-AMOS), 
• CB-SEM (IBM-AMOS), 
• Consistent PLS and 
• Regular PLS.

We can handle Higher order constructs too here and there are many other functionalities.

I've provided the introduction to this package on

All the data files, presentations, R-Script files are available in this folder:

7. No Happy New Year, Happy Diwali, Happy Holi, Happy B'day, Happy Anniversary etc. allowed on this group.
8. Few months back there was a facility for asking & sharing the Research Papers. Now there is no provision of asking for the research paper here.
 
Let’s make a better research environment.

Dear Friends

It is recommended that Consistent PLS (proposed by Prof Henseler) shd be used when all constructs are Reflective and Regular PLS shd be used when the constructs are a mix of Reflective and Formative or all formative. But in practice, scholars use Regular PLS for all purposes.

SEMinR provides estimate_pls function for both the PLS: Regular and Consistent.

When Constructs are defined as Reflective, we'll get the results of Consistent PLS and when constructs are defined as Composites, we'll get the results of Regular PLS.

I've explained the working on Consistent PLS using SEMinR package in this video:

Dear Friends

The Regular PLS can be used in SEMinR very comfortably. The complex models can be drawn very easily here. I've explained the working of Regular PLS using SEMinR in this video:

Dear Friends

Working on higher-order in SEMinR package is very simple. Though the results of the second-order constructs are not exactly the same but quite similar to that of SmartPLS.

Dear Sir

Thank you so much for explaining each and every step of SEMinR package in R studio.

I have one query related to last video SEMinR Part-6 Working on a model with one Higher-Order Constructs.

Sir in this smartPLS Model constructs seem reflective, if I am not wrong... but sir while explaining measurement model in R Studio you have written command Composite. Sir what i understood composite command used for formative construct...

So please clarify this confusion...I will be very thankful to you respected sir...

Every package has its own syntax (way of writing)

In Confirmatory Composite Analysis (CCA) and R-Package cSEM, composite is considered different from a construct. A construct may be Reflective or Formative but the Composite is totally different from these two.

In some packages, the composite word is used for the Formative construct.

In SEMinR packages, if you wish to have Regular PLS Calculations, define your construct as Composite

If you wish to have Consistent PLS calculations then define your construct as Reflective.

Due to the same word used in different content, there is this confusion.

Dear Friends

Working on Moderation in SEMinR need just 2 lines more in the existing code of Regular PLS-SEM.

We've to introduce a new construct Interaction in the Measurement code and add the same in the structural code.

Dear Friends

So far we were learning SEMinR from the CRAN Tutorial and the vignette but no Dr Sandeep Singh told me the Open Source book Partial Least Squares Structural Equation Modeling (PLS-SEM) Using R by Joseph F. Hair Jr.,G. Tomas, M. Hult, Christian M. Ringle, Marko Sarstedt, Nicholas P. Danks and Soumya Ray

Dear Friends

In the book 'Partial Least Squares Structural Equation Modeling (PLS-SEM) Using R' by Joseph F. Hair Jr., G. Tomas, M. Hult, Christian M. Ringle, Marko Sarstedt, Nicholas P. Danks and Soumya Ray the authors have differentiated between the terms Explanation and Prediction.

The statistics R2 is used for the explanation part but it is not enough for the prediction. For the prediction, we have concepts like Blindfolding and PLS Predict.

I've explained the PLS Predict in this video:

Dear Friends

While discussing the SEMinR package, we saw that it provides AMOS like output in terms of Model fit indicators as well as Reliability and Validity. But, there is no direct output of Modification Indices. 

However, we can still improve the model fitness but associating the error terms of the most related variables. I've explained this concept in this video:

Thanks for sharing the information with us.

However, the error is coming while running estimate_pls. (please refer attachment)

Dear Friends

Whenever we have a control variable in our analysis, we use Hierarchical Regression for the same.

Now, Hierarchical Regression is available only on SPSS, R-Studio, and a couple of more software (Not available in SmartPLS, AMOS, Adanco, etc)

One scholar asked the query: How to check the moderating role of a var in the presence of a control var?

I have explained the steps for the same in this video:
