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
