Model 2 results_forum.pdf | 95.6 KB |
Hello,
We would like to conduct a METASEM for a model with three variables: Mov (dependant); Psy & pai (independent).
I used the R codes available in Cheung and in Hagger 2018. Unfortunately, I have an error to determine the indirect effect of Pai on Mov through Psy. I can only have the direct effects between the three variables.
I think the problem occurs in stage 2 :
> random2 <- tssem2(random1, Amatrix=A1, Smatrix=S1, diag.constraints=TRUE,
+ intervals.type="LB", mx.algebras( Ind=mxAlgebra(PaitoPsy*PaitoMov, name="Ind"))
Thanks for your help,
Guillaume
Hi Guillaume,
Could you attach the R code in plain text? It's difficult to work with the PDF.
Best,
Mike
Hi,
Thank you for your help!
Here is the script in text and R files

Hi Guillaume,
Please see the revised code. It seems to work fine.
Best,
Mike
Thank you so much for your help!
Best wishes

Dear Mike,
I am trying to perform the MASEM with some missing variables. You previously helped me the code, but now that I have included more studies with some missing effect sizes, it doesn't work anymore when I perform this function :
fix1 <- tssem1(Studiestest10$data, Studiestest10$n, method="FEM")
summary(fix1)
You can see the script attached.
I saw in Hagger 2018 and in some of your papers that we can include studies with missing effect sizes, isn't it ?
Thank you so much for your help,
Guillaume
Hi Guillaume,
You may try the following code. It works for me.
Best,
Mike
