 |  |  |  |
In general, it is possible to specify similar models using PROC MIXED. The following syntax illustrates the relationship for the different specifications:
One-way fixed effects model
PROC PANEL; PROC MIXED;
ID STATE YEAR; CLASS STATE;
MODEL Y=X1-X10 / FIXONE; MODEL Y=X1-X10 STATE /SOLUTION;
RUN; RUN;
Two-way fixed effects model
PROC PANEL; PROC MIXED;
ID STATE YEAR; CLASS STATE YEAR;
MODEL Y=X1-X10 / FIXTWO; MODEL Y=X1-X10 STATE YEAR /SOLUTION;
RUN; RUN;
One-way random effects model
PROC PANEL ; PROC MIXED;
ID STATE YEAR; CLASS STATE;
MODEL Y=X1-X10 / RANONE; MODEL Y=X1-X10 / SOLUTION;
RUN; RANDOM STATE;
RUN;
Two-way random effects model
PROC PANEL; PROC MIXED;
ID STATE YEAR; CLASS STATE YEAR;
MODEL Y=X1-X10 / RANTWO; MODEL Y=X1-X10 / SOLUTION;
RUN; RANDOM STATE YEAR;
RUN;
