APOLOGIES FOR CROSS POSTINGS
This query is related to an earlier posting on the allstat mailing list,
which asked for clarification on the definition of multivariate analysis.
In particular, I now seek further clarification on whether multilevel
analysis is multivariate.
If multivariate == multiple response, then multilevel is not multivariate
unless there are multiple (>1) response variables?
If multivariate == multiple (random) variate, then two scenarios arise:
1) multilevel IS multivariate because it has at least two random variables
(associated with each level of the hierarchy)?, or
2) multilevel IS ONLY multivariate when covariates are allowed to have
random variation?
TIA, Mark.
