### Structural equation modeling made easy with WarpPLS: YouTube video

Conducting a basic structural equation modeling (SEM) analysis using WarpPLS is relatively easy. The software takes the user through 5 steps, from project file creation to model building (using a graphical user interface) and viewing the results of the analysis. Take a look at the Youtube video below.

The link below should take you directly to the video on YouTube, in case you have problems viewing the video above.

Choose the high quality (HQ) option for viewing the video clip above, if it is available (usually at the bottom of the video screen), and expand it to the full screen mode.

As you'll see at the end of the video, the project file is quite small, and it contains everything that is needed for the analysis. The file can be copied into a separate file, which the user can then open and change, by modifying the model for example, to conduct a different analysis.

Brilliant demonstration - thank you !

Thanks Scott, glad you liked it.

Hi Ned,

Congratulations on an easy to use and very effective program. I have 1 question,I am conducting a comparison study between two countries and using same model and i wanna to see which model is better. so based on my results i got two models with different fit indices but if the most of the indices are same value(eg. APC1=APC2= ,263 and so on for the other some indices my question is which the indices are more critical in the choice between the two model? (e.g. APC or ARS or AVIF etc..?

thanks alot

Gomaa

Hi Gomaa.

We still need research on how to use the model fit and quality indices to select among models; especially research building on Monte Carlo simulations, where we know true values.

Having said that, an index that I would place some confidence in, for selection among models, is the average adjusted R-squared (AARS). This index is available in version 4.0, which I also highly recommend.

Hi Ned,

Congratulations on an easy to use and very effective program. I have 1 question,I am conducting a comparison study between two countries and using same model,i rely on the path coefficient and standard error in calculating t-statistics so i want to know which formula should i use to calculate t-statistics, as well as the formula to calculate P-Value?and after i calculate both ( t-statistic, and P-value how can i take the decision? which means how can i know there is a differences or not?

many thx in advance

Gomaa.

I think what you are looking for is here:

Hi Ned,

I am conducting a comparison study between two countries and using same model, to identify the differences i use T- statistic. i did find a formula to calculate t- statistic, but didnt find a formula to calculate P value? so how can i calculate P value from t- statistic?

Many Thanks in advance,

Gomaa.

Hey there. Is there any research article that has used WrapPLS and reported the results i.e., simple path analysis, mediation and moderation. If yes, can you share it? Thanks

Hi Gomaa, see the Excel files linked here:

Hi Ned,

How to obtain unstandardized path coefficient using warppls?

Thanks.

Hi Anon. They are available from the ustd. graphs. See page 102 from the v. 7.0 Manual:
