Hello dear uesRs,
I am working on modeling both level one and level two heteroscedasticity in
HLM. In my model, both error variance and variance of random intercept /
random slope are affected by some level two variables.
I found that nlme is able to model heteroscedasticity. I learned how to use
it for level one heteroscedasticity but don't know how to use it to model
the level two heteroscedasticity. I wonder if anyone could give me some
guide how to do it or any suggested software / packages if nlme is unable to
do it.
Many thanks in advance!
Best,
Yen
