How to do SEM in JASP?

What is the first thing I have to do? My IV, Mediator, and Outcome are the multidimensional variable. I am confused how to the SEM.

How to see the valid items?

What to do to count the reliability? is it with the valid items or before valid item?

Thank you

  • We use Lavaan syntax. There is help available online (YouTube?), there is the help file (blue circle with the "i") and you can check out the examples in the JASP Data Library.

  • Thank you for the response.

    I will see how it goes with my case.

  • Hi Niar,

    You can get JASP help files by clicking the blue circle with an "i" on it -- in the GUI for SEM. However, for SEM it is relatively concise, and I've copied it here:

    Perform structural equation modeling (SEM) using lavaan (Rosseel, 2012). Go to lavaan.org for tutorials on the model syntax. See also Kline (2015).

    For additional reading, see https://osf.io/xkg3j/ for an introduction to SEM in JASP, by Burger & Tanis.
