Hi everybody,

I want to use proc mixed, with this model ,

Y= x1 +x2 +x1*x2
question :
How proc mixed handle the missing value for estimating the effect.of
X1 or X2 when :
- Y is missing
- X1 or X12 is missing.
- both Y and X1 or X2 are missing
thanks,

PROC MIXED will not use observations where the response Y is missing;

PROC MIXED will not use observations where one or more predictor
variables have missing values
