PROC MIXED Estimation Method

Use the drop-down menu to specify the estimation method to be used for the covariance parameters of continuous trait types and a model that includes random effects. PROC MIXED is used to perform the estimation.

 

Method:	Definition:
ML	The ML specification performs maximum likelihood and is the default method..
REML	The REML specification performs residual (restricted) maximum likelihood.

Refer to the SAS PROC MIXED documentation for additional details.
