I try to use MixedModels.jl.
Is any documentation how to translate SAS/SPSS random/repeated covariance type to julia MixedModels.jl notation?
RANDOM Fact1/TYPE=FA0(2) SUB=Fact2 G; REPEATED/GRP=Fact1 SUB=Fact2;
where Fact1 and Fact2 - factors.
How to fit:
- CSH (Heterogenous compound symmetry)
- UN (Unstructured)
- VC (Variance components)
- AR1 (First-order autoregressive)
How to explain the relationship between these types and Julia MixedModels.jl notation to SAS users?
