title: Options for dual domain latent growth curves (perhaps in lavaan?)
body: <p>I am trying to analyze three repeated measures of two outcome variables. It was recommended to use a latent growth curve model. I know in some software (SPSS) you can make growth curves with multiple measures, but it doesn't seem as straightforward in lavaan. Reading the lavaan tutorial it mentions multilevel SEM using sem() - is this appropriate for a repeated measures dataset? Or is there another package that allows multiple outcome growth curves in R?</p>
