| Subject | st: Wondering why default estimation in xtmixed was changed from REML to MLE in V12 |
| Date | Wed, 7 Dec 2011 14:39:29 -0500 |
Does anyone know why xtmixed changed from REML to MLE for the default estimation method in version 12? My understanding is that REML estimates of variance components are less biased than MLE.
