Re: MU referencing
Hi,
Could we modify the inter-occasion variability example (example. # 7
in the intro7 guide with NM7.1 installation) to inter-group situation
?
MU_1=THETA(1)
TVPAR = EXP(MU_1+ETA(1)) ; fix ETA(1) to a small value ?
GRP0 = EXP(ETA(2))
GRP1 = EXP(ETA(3))
IF (GRP.EQ.0) GRPETA = GRP0
IF (GRP.EQ.1) GRPETA = GRP1
Param = TVPAR*GRPETA
Thanks
