I’m a graduate student in bio-statistics and I need your help very much on a SAS syntax explanied below. I really appreciate if you could help/guide me on this request.
I’m trying to create a syntax on Covariance Structures in Repeated Measures Analyses (Unstructured General AR (1) Compound Symetry). In the syntax, I have been trying to write codes that generates repeated data with a normal distribution and with correlation between measurements of each record (patient i.e. 201, 202, 203, 204 in the example below).
