Dear All,

 

With NM7.2/SAEM, the root.phi output file contains the conditional means
(and variances) of the individual phi's (mu(i)+eta(i)) - which is great!
I found that the these values can be different from what you get from a
$TABLE  in more classical way:

 

$PRED

MU_1=THETA(1)

K=MU_1+ETA(1)

...

$TABLE K ...

 

For a some subjects, these are very different, and the ones coming from
the $TABLE are clearly less optimal, yielding a bad individual fit, as
judged from IPRE calculated in $PRED.

 

I guess  one part of the solution is using CPRED and CPREDI - but
unfortunately I cannot use these as I (have to)  use LIKELIHOOD in $EST
(M3 method for BLQ-data).

 

 

Kind regards,
