Growth Curve Model with Non-normal data PreviousNext

I am working with data that are right skewed. That data are continuous in that they could be any real value between 0 and 100. I am wondering about the most appropriate way to estimate a growth curve model with these data. I imagine I could transform the data so that they are normally distributed. My other hunch is to use a robust estimator. Some guidance would be appreciated.

Depending on the substantive setting, you could

use MLR

log transform

use the skew-normal or skew-t distribution.
