hi, there,
I am a newbie of jamovi, trying to do multilevel analysis. There are YouTube tutorials , but only 2 level mixed model. Any examples or more detail steps for 3 or more levels of data?

Hi
there's nothing special about 3-level mixed model as compared with 2-level ones. You just want to be sure that your clustering variables are coded in a suitable way. Let assume you have districts, schools, and classes (I know it's the cliché example, but it is useful here). You need each class to have a unique value, each schools its own value, and each district a different value. Something like this

Code: Select all

Di    Sch    Clas  
1       1        1
1       1        2
1       2        3
1       2        4
2       3        5
2       3        6
2       4        7
2       4        8
3       5        9
3       5       10
3       6       11
3       6        12



When you have this coding schema, you simply include districts, schools and classes as cluster variables and decide what coefficients vary across each cluster variable, as you do with 2-level models.
