Random slopes in multilevel models

[Steffen Nestler]

Hi Terrence, hi Yves,

I know that it is not possible to estimate multilevel SEMs with lavaan. However, I was wondering whether there is already a supported lavaan-syntax for such a model that I can use with lavaanify and lavMatrixRepresentation? For instance, something like this 

m <- 'level: 1
fw1 =~ happy + calm
fw2 =~ active + relaxed
s | fw2 ~ fw1

         level: 2
fb1 =~ happy + calm
fb2 =~ active + relaxed
fb2 ~ fb1
        s ~~ s'

test <- lavaanify( m )

lavMatrixRepresentation( test )

where "s |" is the random slope.

Thank you!
Steffen
