PLS-SEM model sintax

ArrayaM

Good morning

I would like to know if the process of building a model in the PLS-SEM version (model syntax) is the same as SEM.

If there are differences what are they?

Is it possible to have an example?

Thanks

Pretty much the same syntax, except that formative constructs (i.e. composite variables) are specified using the <~ operator (e.g. "f1 <~ item1+item2+item3+item4)

You can probably get more info by clicking on the "i" information button in the analysis, but IIRC the library used is cSEM, so you can Google examples using the cSEM library in R

Thanks.

However, is it this sintax well done?

Model <- “

NFP ~ DCS

FPR ~ DCS

 

# Composite model

DCS <~ SEI1 + SEI2 + SEN1 + SEN2 + TRA1 + TRA2

NFP <~ NFP1 + NFP2 + NFP3 + NFP4 + NFP5

FPR <~ FPR1 + FPR2 + FPR3

“

In the meantime, I tried to improve the syntax but JASP always gives this error (image).

I ask for your help.

No need for model <- "...", only the model in the dialog box. No quotation mark, no assignment to a variable called model. Only the model syntax

thanks, and now I have a new error

I have the same problem. Can someone help us with the syntaxes? Thank you very much!

At a minimum this is not an informative error message. I'll ask our expert.

Cheers,

I know fairly little about PLS-SEM, but without the data set there won't be much any of us can do to find the error.

It would help a lot if you could create a GitHub issue: https://jasp-stats.org/2018/03/29/request-feature-report-bug-jasp/ and upload the data set there. If that is not feasible, you might also upload the data set here or, if private, send it to us at issues@jasp-stats.org.
