Hi,
I am a new NONMEM user. I have a question about mixture distribution.
I have two parameters. How to apply mixture distribution on the both
parameters? I should use the first one or the second one?
*First,*
$PRED
IF (MIXNUM.EQ.2) THEN
ALPH =THETA(1)
END IF
IF (MIXNUM.EQ.1) THEN
ALPH = THETA(2)
ENDIF
IF (MIXNUM.EQ.3) THEN
BASE=THETA(3)
ELSE
BASE=THETA(4)
END IF
$MIX
P(1) = THETA(5)
P(2) = 1-THETA(5)
P(3)=THETA(6)
P(4)=1-THETA6)
NSPOP = 4
*Second,*
IF (MIXNUM.EQ.1) THEN
ALPH =THETA(1)
BASE=THETA(3)
END IF
IF (MIXNUM.EQ.2) THEN
ALPH = THETA(1)
BASE=THETA(4)
ENDIF
IF (MIXNUM.EQ.3) THEN
ALPH = THETA(2)
BASE=THETA(3)
ELSE
ALPH = THETA(2)
BASE=THETA(4)
END IF
$MIX
P(1) = THETA(5)
P(2) = THETA(6)
P(3)=THETA(7)
P(4)=1-THETA(5)-THETA(6)-THETA(7)
NSPOP = 4
Thank you very much!
Best regards,
Kehua
