y*****w 发帖数: 1350 | 1 The STATA codes are as follows. There are 3 separate codes, labeled as 1),
2), and 3). How to convert them to SAS codes?
1) xtmixed bwtsds epold epolmn || pair_no:, reml
2) xtmixed bwtsds epold epolmn || pair_no:, reml
est store B
3) xtgee bwtsds epold epolmn, i(pair_no) rob
lincom epolmn-epold
The first two codes are for generalized least-squares (GLS) estimation in
mixed models. The first is the REML method, and the second is the ML
method for variance parameters. The third code is GEE estimation.
